There's an obvious moral dilemma here. Like the one about if you had access to a time machine, would you kill Hitler as a baby?
If Trump recovers and continues to govern in a way that kills people, is it moral to wish him to return to office?
I hope he does not, without expressing an opinion about his illness. That's the end of the dilemma that matters to me. Not him. The people who he will damage. He has power. They do not. He has choices. They do not.
I hope the person whose evil policies kill people doesn't get to kill people any more.
