Harming animals in youth

I think I put a magnifying glass to ants once, or maybe I just watched. Either way it was a long time ago. The last animal/insect I killed was a spider I found in my shower. I took it with a tissue and flushed it down the toilet.
I've never killed anything more than an insect.

 

Now, that I think about. I tried to hit a bird with my slingshot, but I missed and hit my neighbor's car. I guess that's what you call karma.

 

I only kill flies and mosquitoes cuz they always ruin BBQ's
