Already have. I think killing CEOs who contribute to endless human suffering is right, and defending those people from those who’s lives they’ve ruined unjustly is wrong. Next question.

kill everyone we don't like

Kill people who purposefully, pointedly, and knowingly cause harm, human suffering, and sign death warrants for people who could have otherwise survived. Robbing life and money from families whose kids or parents need treatment, and sending these people into bankruptcy. Or straight-up denying life-saving treatments.

And these people know they're killing people, but they don't care because they're making so much money off of it.

So no. It's not "everyone we don't like." It's people who purposefully profit from doing harm at the cost of human lives.

This isn't a "Is killing a person that insulted you right or wrong?" moral conundrum, it's a "If you could kill Hitler after he had started exterminating people, would that be right or wrong?" moral conundrum.

Most people who would say "it's the wrong thing to do" for the first one would say "it's the right thing to do" for the second.

Mind you, the really right thing to do on the situation with this CEO would have been for the State to do its fucking job and protect the people from mass murderers like him, but it refuse to do so, hence here we are in a bad situation.

It was a bit messy for the French but they haven’t had a king since.
