So like almost everything in history, ever?
Rarely has there been a major historical event where 'the winners' didn't do bad things? Do we think the Allies in WW2 were all saintly? No, but they were better than Nazis and Fascists.
And, as you have just shown, the negative aspects are widely acknowledged. Unlike in the previous cases mentioned, which have been very heavily sanitised to the extent that most people don't know what happened. More like wartime propaganda of WW2.
As a counter-example to the first example, there's the voting reform campaigners who actually did the work. They didn't commit crimes solely for the purpose of getting arrested so they could lie about it and say they'd been arrested for campaigning for voting reform. Not that they would have had to - in many cases they actually were arrested for campaigning for voting reform. In some cases killed, the best known example being the Peterloo massacre. They also didn't attack people, commit arson and plant bombs in public places to kill as many people as possible. The suffragettes came along near the end of the campaign, did all those things and only stopped because they decided they wouldn't get away with them during WW1, so they switched to harassing men instead. It's more likely that the suffragettes delayed women getting the vote than that they hastened it. The government didn't want to be seen to be giving in to terrorists. There had already been 4 major voting reform acts before the suffragettes even existed, the first establishing nationwide criteria for who had the privilege of voting and the following ones each extending the number of people with the privilege of voting. The next one, which would have happened soon anyway, was universal adult suffrage. As an aside, another difference that I think is important is that the voting reform campaign groups were themselves democratic and operated on a one member one vote basis whereas the suffragettes weren't and didn't. They were out for power, not democracy.
As another aside, one of the major Allies was worse than the non-nazi fascists (Italy and Spain come to mind) and arguably as bad as the nazis.
But none of that changes the point that it's not certain that any group that does bad things will later be beatified by a very well executed and sustained propganda campaign. Even if they win and become the dominant power, it's still not certain.
