Tell that to Rebecca Sugar or /r/Stevenuniverse, where they get absolved and forgiven despite waging millennia of war and destruction

Some choice quotes spread across the series from the main antagonists (or at least they were at the point they say them)

All this life that's been growing wild here on Earth... None of it will survive my invasion. We're not creating life from nothing... We're taking life, and leaving nothing behind

Now the impurities you've encouraged in them are gone. Now they are brilliant! Now they are perfect!

Show everyone you're unfazed by this little uprising. Your Gems will fall into line, and these Crystal Gems will be no more. As long as you are there to rule, this colony will be completed.

How did you even survive? We blasted the planet and obliterated every gem on its surface.

. We all must make sacrafices, for the sake of our perfect empire!

I want my Cluster, and I want that planet to die. Just make that happen.

And yet by the time the series progresses /the recently released film starts, all of the characters who say the above are considered friends. The villian:redemption ratio is higher in Steven universe than my little pony and for all the wrong reasons.
