Tito 

Was Josip Broz Tito a criminal? He was a communist dictator, and during his reign, people were murdered, imprisoned, and persecuted for disagreeing with the regime. Innocent people suffered in the frenzy of the Partisan's revenge that followed the WW2. So in that sense, yes, undoubtedly, he was a criminal. On the other hand, he, and his Communist Party, were the ones who got Croats to fight the nazis and the fascists after Yugoslavia was overrun, while the other politicos either jumped to the opportunity to collaborate (and in the process, become even more zealous butchers than the nazis were), or sat on their asses "passively resisting". It was thanks to him that we, the Croats, were on the winning side when the war ended. It was thanks to him that we avoided becoming one of Stalin's provinces, like the rest of the Eastern Europe.

Now... Should we name our streets after the guy? I think it's sick that we're even asking ourselves that question.
