I was born in 1993 in rump Yugoslavia so I can't say I know all but I picked up something while I researched some stuff about 90's.
From my shitty opinion:
Milosevic wanted to be new Tito like figure.
But he couldn't sustain Tito's Yugoslavia, only thing he could do to gain power is to use Serbian nationalism for his goals.
FR Yugoslavia was new country formed in 1992, from remaining two states in Yugoslavia: Serbia and Montenegro.
Plan was to expand that new Yugoslavia with new territories that would be Serb republic in Bosnia and Serbian Krajina in Croatia.
But he didn't have all power, he had to make coalitions with nationalist parties like SRS led by Vojislav Seselj.
He wasn't against minorities and other nationalities like Croats and Bosniaks.
I remember I read somewhere that in some meeting there was discussion about some Muslim being government official in Budapest or something like that, but him being Muslim was problem for some who didn't want him on that position, Milosevic said something like: He is citizen of FR Yugoslavia.
Meaning that it does not matter that he is Muslim and he should be treated like citizen.
I remember that my school still had name of some communist child hero, which after fall of Milosevic got renamed to Serbian leader of 1804 uprising.
And it wasn't only case of such renaming.
There was one surviving chetnik from WW2 from around my town, who only returned to his village where he was born after Milosevic's fall.
I remember seeing another older man wearing beard and chetnik uniform also after fall of Milosevic.
Stuff like that wouldn't probably happen during his rule.
Again, don't use this as any evidence, it's just some personal observation.
Albanians were retards, they were creating troubles even when Tito was alive and especially after his death.
