Were there any famous or powerful Romans we might consider more liberal/progressive by modern standards? People who didn't believe in wantonly enslaving and plundering and conquering, or exploiting populist rhetoric, or otherwise abusing people. People who made reforms without ulterior motives (or at least with benevolence and empathy as some of the genuine motives).

(One can argue there aren't many powerful people like that even in modern times, but I can at least think of a few. Just wondering about Roman history, though.)
