I think everyone I know is slowly killing themselves and I don't care.
How can you not care? How is this effecting you having these thoughts?
I like to see them doing self-harm.
Wishing others would self-harm doesn't help them in their time of need. Ignoring their cries for attention will get someone killed.
I just want to see their blood and I don't care what happens to them.
You need to be a more caring person. It's wrong to not care about others lives like that.
