Edit: However, fighting because of what faction was worse in a conflict that ended more than 80 years ago is nonsense. This comment was made only to remind all that both factions made war crimes.
Franco supporters' oppression aginst the losers side ("Republicans" and Communists) was worse after the war, from what I know.
All my grandparents were pro-Franco (some more openly than others). I have done my own research and I have concluded that no, they were the baddies. Of course the other side were not all angels. They never are.
> ended more than 80 years ago
The problem is that that conflict from 80 years ago had ramifications that continue to exist today, even present in our Constitution.
Both sides, did some awful and unmoral things, but the nationalists did a lot more awful things. Like bombing fleeing refugees. Also, the nationalists ended consolidating around the falangists and pro-nazis ideologies, and getting military help from fascists Italy and Nazis. When we ended the civil war, we had to endure a fascist regime to the end of 70's. And we endure yet some sequels of this.
So, please, don't reduce the civil war as "hate and violence between neighbors in the name of extreme political ideas". It's was an bloody military uprising against the legit government that the people elected, that ended with fascists on power.
