I love seeing my friend fail at stuff
You find enjoyment in your friends' failures? Why?
Yes, because then I can feel superior to them.
A friend celebrates their friends' accomplishments and consoles them when they fail.
What gives you the right to criticize me?!
I'm concerned that your attitude will result in your unhappiness, frustration and loneliness in the long run. You should explore why you have these feelings with a counselor.
