Come on don't you remember how horrible you were as a kid at times?
I feel sorry for you as well as I'm marrying and children will probably follow.
But also see that by teaching them how to behave, to be nice and polite that you will be rewarded by helping to bring up a decent kid and not a sadistic bully.
It's hard work and then some I see from what you've said. If you wanted it easy you should have had a pet hamster instead
