the point of the bizarro world comment is that it's just incredibly strange to see someone extending sympathies to a war criminal and all around human rights violater. in fact, his administration probably harmed you and your family in some measurable capacity. the same goes for any president, before anyone objects and points out that none of them have perfect track records. that's understating it. they have horrendous records.
he doesn't deserve our respect just because he we was a president or public figure. he didn't earn that. in fact, it's for those reasons he has earned our disdain.
but not feeling sorry for his potential death doesn't mean wanting him to die or even believing he deserves death. it's just that it's incredibly unsettling to see people extending sympathies and even honoring men who have lived long, privileged lives, having earned comfort and prestige despite the fact that they have committed atrocities which warrant life in prison by any fair estimation.
dude is 90 and jumping out of planes and having the time of his life after contributing to hundreds of thousands of deaths while a kid like chelsea manning is serving most of his life behind bars for leaking government secrets.
i don't want him to suffer. he's a human being. but if he dies, i won't care, and i am not required to.
so if you are extending sympathies to him, fine. go for it. but if you were sitting there feeling good about the death of say, hugo chavez, you should really be questioning you are deriving this "moral" sentiment from? it's either ignorance or approval. and the latter just doesn't make sense.
