You don't know ANYTHING at all about the killer.
I know that he killed a man who started praying next to him in the hospital room he was in.
That makes him a murderer.
Murder is, by definition, wrong, and not right.
Therefore, he is not right, and certainly not in his head.
"Right-wing" means "conservatory or reactive."
Murderers are, by definition, NOT conservative, because they do not conserve life.
That places him squarely in the wrong.
and voted for Trump twice-
Re-publicans vote for Dumbocrats (and vice versa) all the time. Doesn't change their political or moral stance.
Which indicates that he is seriously mentally ill, and ill enough that he killed a man because he started praying next to him.
Such actions deserve the death penalty.
Maybe he is a homosexual Martian?
He's not, because Martians are, by definition, people from Mars.
He is human, and all humans are from earth.
Ergo, he is not a Martian.
Maybe he is a Catholic hating Baptist?
Doesn't change the fact that he's a leftist, judging by his actions.
God is right.
Murder is wrong.
The man murdered his hospital room-mate. That puts him in the wrong and on the left, because God is right.
Again, I know that he killed a man because he started praying.
That excludes him from being in the right.
