I’m very slightly ashamed for what I think they should do with him once caught.
. . . turning him loose with some Marines . . .
on a deserted South Seas island with no witnesses . . . could be fitting . . . amongst other possibilities.
Thankfully, vengeance is God’s. But He also ascribes to authrotities His retribution . . . such as executions.
Well....imho, it's righteous anger. This is immoral and evil. The guilty person(s) should pay for the devastation and loss of life. It is no different than committing murder.
