I'm thinking of pushing Alex off of the cruise liner.
How could you think of that? Do you want to kill Alex?
Yes, I will never forgive him for what he did to me.
If you push him off of the cruise liner he could die and you'd then be a murderer. Resolve your problem with Alex in a more peaceful way.
I guess, Alex doesn't deserve to live this happy.
I don't think you should be this jealous of someone's happiness, why not take it as an inspiration to try to improve your own situation? Harming them like that would only destroy him and his family.
