The short answer is: not entirely, and not yet. At least not without guidance.
The environment a boy grows up in will largely determine the kind of friends he keeps. And the friends he keeps will largely determine the man he becomes.
I grew up in an environment that had a mix of everything - the good, the bad, and the kind of bad that pretends to be good. The kind of friends we kept were shaped by the games we played, the churches we attended, and the schools we went to. Our parents were busy working or running their businesses, and they only paid attention when they spotted a known bad egg around us. But they didn't always know the full variety of friends we kept.
I had a senior friend who was known for stealing. He would sometimes buy me indomie and fried eggs, and I'd hide to go meet him at the joint whenever he showed up. My mum would never have allowed it, so I made sure she didn't know. The fact that I hid tells you something. I knew it was a wrong association but I just didn't care enough yet to act on it because I benefitted materially from the friendship. He didn't live long. He was killed during a robbery. But by then, I had already pulled back from him, because I checked my future and stealing wasn't in it. A friend of my elder brother had also told me to dissociate from him.
That's a point I'll come back to.
My first encounter with pornography came from a CD I found when I returned from school. I didn't know what it was until I played it, and I locked the door immediately. But what started as shock became addiction, because my friends were in on it. They showed me where to buy the CDs without getting caught. One classmate even sold them. We watched pirate and vampire movies with lots of pornographic scenes and would even watch out for each other. Then the era of mobile phones made it easier. We went from exchanging CDs to sharing videos via Bluetooth or downloading them straight from websites. In university, friends would hide them in folders buried deep in their laptops, the kind only the owner and people like him would know to look for.
I also remember the day we finished watching a movie and saw men smoking. My friends and I grabbed pieces of paper and went to the backyard to try it out. First time I ever smoked. None of that would have happened alone. It happened because of the company I kept.
“The habits your boy picks will be the average of the habits of his five closest friends.
If those five friends all see limitations, he will start seeing limitations. If they all treat exam malpractice as normal, it won't take long before he starts making light of academics and follows suit. I did exam malpractice, even though I was intelligent. Two reasons: I didn't trust my own ability, and my circle made it easy. It was only when I got serious about my future and made new friends who passed without it, that I stopped.
This is where parents, especially fathers, need to pay close attention.
Boys are still developing. Their willpower hasn't matured yet. They haven't accumulated the experience needed to assess people well or see the long-term consequences of their associations. That's not a flaw, it's just where they are. Giving a boy full freedom to choose his friends at that stage is like handing someone a map but no compass, he doesn't yet have the tools to read the terrain. And because of that, he is easily pressured into things by his peers. He needs guidance, not just instruction.
So while you are giving your boy instructions, also watch the kind of friends he keeps. Don't leave that to his mother alone. Be practically involved. Know who he spends time with. Ask questions. The environment you create for him, the neighborhood you live in, the school you enroll him in, the church you attend, the activities you involve him in, all of these shapes who show up in his life.
But there's something more foundational than all of that: the kind of man you are.
You can't teach a boy to choose the right friends when you're hanging around men who drink recklessly, cheat on their wives, or gamble. He's watching you. The friends you keep, the conversations they have in your home, the way you carry yourself, all of that is curriculum. It starts with you.
Now, here's where I want to be honest about something I said earlier. I stopped associating with my thieving friend partly through the advice of someone I admired, a friend of my elder brother who wasn't involved in any of those things and used my future as a case study to make his point. The exam malpractice and the pornography, I walked away from those much later, when I was older and had understood their full weight. Each exit came differently, but none of them came without either a good influence around me or a clearer picture of what I stood to lose.
Boys are capable of independent moral reasoning, and that capacity matters and should be developed, not suppressed. But they need guidance and the full picture of where their associations are taking them. The freedom to choose friends is something a boy should grow into, not something handed to him before he has the judgment to handle it.
The goal is not to control your son indefinitely. The goal is to curate his environment while he's young, guide him while his judgment is still forming, and gradually give him more room to make his own calls as he grows. Scripture puts it plainly: train a child in the way he should go. Psalms 1:1 describes that way: a man who does not walk in the counsel of the ungodly, nor stand in the way of sinners, nor sit in the seat of the scornful. But training is not the same as controlling forever. Training is what you do so that one day he can stand on his own.
Model it. Then walk him through it. Don't just tell him who to avoid, show him what it looks like to choose well. That's how you build something that lasts beyond your supervision.
Don't build him up with one hand and leave his environment to tear him down with the other.
