I dunno, the guy was able to mind control Megatron. I’d consider that a pretty big W on Comic Sombra’s part
I still have a hard time accepting Cozy Glow as a legitimate canon pony. She really messed up a years long perception that ponies are generally good in nature and peaceful.
not everyone needs to have some sort of deep/tragic backstory as to why they act the way they do.
some people are just assholes.
As for Sombra… as much as I disliked how shallow he was in his first appearance originally, I did eventually come to appreciate him being kept at a distance and depersonalised - it and various implications likely formed from plot holes let me imagine that he was worse than the show’s rating could directly support, a true Pony Hitler.
