On the one hand I agree that the brutality being exhibited is far beyond anything that can be allowed. On the other hand Isis members are probably individuals - many of which are brutal murders but some of which may be involved for other reason - in particuarly it's easy to imagine someone having legitimate grievances against the United States or the Iraqi forces being in a situation where they've gotten themselves in to the point that they can't turn away from a brutal path. That doesn't excuse them in the slightest; justice demands that prioritize protecting those innocents in the region and if that means killing ISIS fighters than that's the way it goes. But if there isn't room for at least theoretical rehabilitation or change on the part of our enemies than we reduce them to things rather than people, and, in the long run, that might be more problematic.

Worth thinking about though certainly.

Burning humans to death has no excuse.
Selling human beings has no excuse.
Raping thousands of women and children, some to their death has no excuse.
Genocides of the Yazidis has no excuse.
Beheading humans has no excuse.
Corralling and Massacring students has no excuse.

It goes on, and on and on...

Will not fit on a bumper sticker. However someone who is willing to not only do those horrible acts, is also willing to fight a war for their ability to keep doing it, I do not feel can be rehabilitated.

who are purportedly rehabilitated. Some people are just too dangerous to ever be allowed to go free.

People's heads, at at point I considered them all irredeemable.

The world won't shed tears for those disgusting monsters.
