History repeats itself over and over

I guess sometimes, history does repeat itself. I remembered when i was in college, and a friend ask me, hey, why did you pick up history? It is by far the most boring subject ever. I my very intelligent reply then was, history is in fact a very interesting subject. Just a bunch of story reading, remembering some facts, and of course, the part that was interesting was that throughout history, it repeats itself over and over again until someone becomes wise enough to figure out what went wrong, who did it, and how not to allow it to happen all over again.
And sometimes, even when you figure out, what went wrong, who did it, one still allows it to happen all over again. I guess it has something to do with human nature. There is a saying that a leopard never changes its spots. How true. Human nature is a blend of all sorts of characters. Some people are dishonest, some people are cheaters, some people are truly nice and some people will forever be suckers. And the interesting thing is that, human race has survived so long only because there are a variety of people around.
Imagine this, a husband who abuses the wife for the first time, then goes back to her to say i'm sorry, it'll never happen again. And there must be a wife who is silly enough to believe him and take him back only to have the same thing happen a couple of weeks, months or years later.
A guy that cheats on his girlfriend, says the same thing, and a couple of weeks, months, years later is doing the same thing over. And for every person that is the aggressor, there will be a willing victim.
Of course this is merely in a family unit. In society, criminals commit the same crime over and over again, go in and out of prison. And not forgetting the numerous wars that have occurred. Someone is greedy, someone is weak, someone wants more. Sign some treaty, never going to happen again, shit hits the fan once again.
So i guess, history does repeat itself more then once. Question then is, do i want to be the aggressor or the victim?
Stupid question but mostly ending with a stupid answer!
