Most synpathetic for me is Asriel, he's done some pretty bad things to put lightly but it sucks what happened to him considering he started out as just a kid wanting to help his best friend/adoptive sibling no matter how dark the deeds were. Ands kind of a shame no one will know he's the true barrier breaker and his reward is more loneliness. Asgore is a close 2nd for your reasons.

Was hard for me to think a least synpathetic at first, IMO there's only a handfull of really tragic characters and I like them all but outside of that i'd go for Mettaton. Severing family ties for fame is kinda low, but he does redeem himself by the end by reuninting with Blooky and Shyren.
