Thread: Is it bad that when I argue with people i tell them to go kill themselves?

I notice every time I get in argument with one of my brothers they are 11 and 6, I tell them to go kill themselves. I told my mother today to go kill herself because we were arguing about things. I used to tell people at school to go kill themselves too. so is this bad? I'm 13 btw. I just can't help it. I've been doing this since I was 9.
