Very Serious Question about thoughts...?

I do the same think and like that other guy said.... i thought i was the only one. I'm not depressed and i never think about suicide. For me I think it's more of a way to test my self, like i'm asking myself how much I would care or what I'm capable of. I'm not evil lol I'm actually really sweet, I think this is mostly just the different parts of our brains challenging each other.
