Yes, I am guilty. I am a happily married man but every time I see a really beautiful woman I have the deisre to have sex with her. That desire is based on the instinct to procreate and I can't deny that. But what I desire is good hot sex, not fucking some woman against her will while she is crying and begging me to stop. There is quite a difference. And I will not for one minute belive that it is because socciety has trained me that way. I will certainly agree that it is society that tells us we should only have sex with one person. But it is decency and compassion for others, which is part of our being, society or not, that prevents us from raping women against their will.

As for your statement about rape in Africa, I have no knowledge about this one way or another so I will refrain from commenting. What I do know is that there is a tribe of people in Papua New Guinea who are essentially sex freaks. They start having sex when they are young children, have many partners, will have sex anytime, anywhere, in private, public, doesn't matter. There is almost no instances of rape, however, as having sex with an unwilling partner is strictly taboo. So, while these people certainly are giving in to their instinctual desires for sex there is something that prevents them from just taking it. Oddly enough unwanted pregnancy and stds are also pretty much unknown to these people. Seems they know some secret we don't.

As far as revenge is concerned, sure, we have all felt the desire for it. And I, like many others, have acted out on this. But what is this based on? I agree that it is instinct. But my guess is that it is based on the instinct of self preservation. Way back when, if some one eye brow having neanderthal came and stole your wooly mammoth burger you'd go and club the mother fucker and take it back. Not because you wanted to hurt the guy, but because you wanted to eat. it was self preservation. Now if someone comes along and steals my whopper, yeah. I'll probably pop him in the jaw and take it back. Sure, I could just go and buy another one but that old instinct kicks in. But again, the instinct is one of survival, not of a desire for violence.

So, I still definitely disagree that we have an instinct for violence, an instinct to harm others and take what we want. We have an instinct for survival, that's all. Like most animals, we band together in groups to facilitate this survival. And, like most animals, we have rules, some clearly laid out and others unspoken, that define how we act in these groups. As such, it would stand to reason that it is instinct that leads us to form societies and form the laws that goven these societies. Makes sense, doesn't it?
