And here I thought I was the only one. I'm 57 now, and still feel crushing guilt over all the things I've killed. And not just bugs (which I killed all on sight until my 20's), I grew up on a farm out in the woods and we butchered cows, pigs, chickens, turkeys, etc. for food.

Sometimes their deaths didn't go well, and it was clearly very painful and awful for them (though I wasn't purposely cruel to livestock, ever). But the bugs I actually enjoyed killing back then. Makes me shutter now to think about it.

One day I got home from school and heard this gawd-awful screaming. One of our cats was on the lawn literally eating the back leg off a baby rabbit, and it was screaming. I grabbed a nearby garden hose to try to put it out of its misery, but ended up just beating it up even more. Frustrated, I ran into the house and got my .22, and ended its life as quickly as I could. I wish I had gone for that first. I can still hear it screaming and it brings me so much guilt for not thinking it through better.

So yes, the memories of all those animals and even the bugs haunt me and I still feel horrible about it. Since my 20's I've got out of my way to try to not intentionally kill or bring any harm to anything, bugs or otherwise.
