I'm the same but I also had tons of fun killing stuff when I was a youngster. I'd much rather see a teenager out hunting crows or woodchucks (even if just leaving them lay) then in their bedroom playing video games all day. I think God meant for our killing drive to wane as we age. Once we've killed enough stuff it starts to lose it's appeal, and I think that's how it was meant to be. But I say let the youngun's have at it!
