Forget the idiotic notions that Celestia's a tyrant and a troll, Cadence is the true monster!

IMO Cadence is a much better Princess than Celestia – her sentences actually stuck.

So far every single major villain imprisoned by Celestia (that we know of) has managed to escape after 1,000 years of imprisonment and has had be be mopped up by Cadence or the Mane 6 – if it wasn’t for them Equestria would be majorly screwed.
