I don't care about a former coworkers attempted suicide
That is a little harsh. Why do you not care about their suicide?
He was a bad person in general and also a jerk.
Some people are just not nice. Death is sad, even if you are not too kind.
I just don't care and I no longer care. Besides, I am over him already.
Anybody's death by suicide is sad, even if you don't like him. You should try and be more empathetic towards other people's troubles.
