Trump is a narcissistic psychopath who cares about nobody but Trump.

He doesn’t care. They can’t do anything for him so whether he kills them or not is of no consequence to him.

Venezuelans on boats predominately Christian so I think he doesn't give a shit.

Precisely the same as killing anybody, which appears to be nothing at all.

Lack of empathy-acts without guilt.

I guarantee he'd say they are all losers for getting killed.

He doesn't care--he gets off on killing people.
