i didn't like ezio at first, especially when he revealed his reasoning behind him taking leo in. but he wasn't a bad person, just not a conventional one. he wanted to keep the appearance of a heart of stone in front of people to avoid unecessary drama and i can certainly sympathize with this logic. but that was just a facade that came crumbling down thanks to leo. And eventually he cared for the little boy that made his heart human again. RIP Ezio
