Do you think it's okay that I've recently become very interested in keeping an eye on executions?
It depends why you're so interested. Do you think capital punishment is justified?
Yes, definitely. Sometimes I wish someone would try to do something to me, so I could have the chance to kill him.
People have different opinions on capital punishment, but it is wrong to wish for the death of others.  If you are hoping for a chance to kill a criminal, then you are no better than a criminal who hopes for a chance to kill a victim.
But they deserve it because they're criminals.
Even if you think it's justified, it's still inappropriate to take pleasure in someone else's death. I think you should try to figure out why you feel that way.
