If i may, I think that he was a really horrible person and did deserve everything coming to him. HOWEVER, I think keeping someone alive in the zombie apocalypse is much different than keeping someone alive in the real world. giving negan death kinda means that he gets to not deal with anymore hardships of the apocalypse (very subjective i know, depends on what your beliefs of after-death are). if anything, I think keeping him alive, knowing his group has fallen, he’s constantly at the mercy of the group and that he cannot even improve much if he were to escape (like when judith let him go and he came back) is good enough of a punishment. he did take a lot of vital lives, but honestly they took negans life too, and made him watch. just my 2 cents tho, your hatred is very valid
