Well, of course they're going to be shitheads. They're kids, that's what kids do. Weren't you a shithead when you were a kid? I know I was, and I was actually a really good kid compared to my older brothers.
Now it just depends, how big of shitheads are they? Do they like to murder animals for fun, or are they little arsonists who love it when fire dances for them? Or are they just normal, typical kids who act crazy sometimes, and like to push the boundaries to see what they can get away with? If the former, then no, I don't want them. If the latter, then awesome, and can't wait. From what Leo desribes, I'm quite confident it's the latter, so no worries. Nonetheless, I want to be 100% certain about everything myself first.
