I guess the thing is... what does a fall mean eaxctly? Because if becoming evil is inherently "a fall" then sure, that was a fall. But if becoming more sure of yourself and confident isn't a fall, then... that's what I really prefer happening to that character. I don't mean I never want him to regret anything ever or see the value of mercy in any way at all, but by and large... I want him to be someone who isn't motivated by that sort of thing.

Which is why MTMTE never worked for me and even... oh lord that Wreckers one? Didn't really grab me the way they did other people I don't think.

I wouldn't mind a redemption arc for Megatron (well I still would dislike it but I wouldn't be so darned upset by it) if it showed him deciding something he was doing was wrong by his own lights--like, say, "I thought murdering everyone made perfect sense but it just creates Autobots who don't just want revenge but can claim the moral high ground believably enough to never just fuck off, maybe I should be merciful for pragmatic reasons and hey, i remember how this felt"

But "I got carried away into killing everyone" just... no. I mean, if we're trying to present the guy as a genocidal figure (and the "field of flowers" makes me think that was the intended reading), genocidal leaders don't start off sensible and then decide to kill all the Xs. They firmly believe the Xs are evil already, and it's the people they slowly convince to agree.
