I wish my former best friend were dead
Its pretty harsh to wish death on a former best friend.
He was such a jerk and always pretended to be nice to me so I would do stupid things for him.
It is wrong to want people to die because you feel wronged. It is not fair for someone to use you in a friendship.
Nah, I just want him to turn into a zombie.
Thats the same thing as wanting him dead. It can hurt to carry bad feelings from a former friendship but its best to let go of those feelings and move on. Find a friend that deserves your friendship and forget about the old.
