No he doesn’t. Siege of Sarajevo was a war crime as was Mladic’s entire Bosnian campaign. It was an intentional campaign of terror/murder directed at specific ethinc groups - the definition of genocide. Which is different from collateral damage which occurs in wholesale industrial warfare (which we were discussing).
The same pass is also not given to the war criminals on the Bosnian Muslim and Croatian sides either. There were no ‘good guys’ there.
