To clarify, the Witch is the MG sentenced to eternal torment.I'm not really sure if there's any continuity between an MG pushed over the brink and the witch itself, so I honestly don't see it as a massive OMGWTFBBQ. Now if they're at least somewhat aware of what they've become and trapped until they're killed...
Yes, if you get too sad, you die in a horrific way, that's terrifying, but I'm fairly sure in a reality where the laws of physics are more like guidelines and causality itself is unravelling, you're likely to find fates far worse than death. Especially if the Devil was a psychotic Homura like most people seem to believe, then attracting its ire might very well mean an eternity of torment.
Ultimately, what matters more here is less the suffering contest between MGs and the MC, and the fact our MC is more maladjusted than any of the MGs and a clearly indicated danger to people he's around. I genuinely doubt there's a MG in PMMM who's first instinct when in a crowd is to start killing them. I mean, even Homu doesn't have to actively suppress instincts to kill anyone who's around her AFAIK, and I'm pretty sure she's a solid 11 on a 1-10 scale of how shitty an MG's life can get.
Mami is Candeloro and vice versa the same way I am still me even after I go insane.
