I hate how these cartoon writers make characters that have committed genocide as redeemable. Yet if you voted for Trump in their eyes you can not be forgiven. Give me a breakThey're actively fixing the shit they caused and reversing things like the experiments as of the end of Future. Those reviews have zero merit, they're the epitome of bad faith takes.
Edit:
To actually keep this on topic, if you want to criticize a fascist for not being "punished" then look no further than Hordak. He fixes nothing and ends up with an autistic gf and they leave it at that. The Diamonds at least are producing tangible results.
