(Example for his flaws is also the race itself because if you really think about it it becomes clear that he didn't know shit and was just way too overconfident in the corpse actually helping him, which it did to his luck but its peak stupidity mixed with confidence regardless)
All in all I think Valentine is one of the most layered & nuanced characters Ive ever seen, if not the most layered & nuanced one, conceptually so unique yet such a perfect execution, love Araki for creating him
I defly didnt do Valentine justice with this Thread tho so feel free to add more on it if you like
