Animal Cruelty

I was just thinking about it and realized how I think animal cruelty is just so messed up. How could anyone ever feel that it is okay to harm another creature. Then you have those people who are like "well, have you ever killed a spider, that cruel too". Which in a way that totally makes sence, but I wouldnt kill a spider in its own enviroment. If Its dangleing over my face in the shower I might freak and smash it, but if I were walking down the street and there was a spider on the grass, I wouldnt go out of my way to end its life. Seriously, I just wanted to rant for a second. Why would anyone abuse an animal just becuase they have this feeling of domination! Its stupid
