It doesn't matter who you were before, as soon as that hits you your default personality becomes "I hate the world and I wanna kill all the things". It's a plot device at its finest. Basically the sharingan's powerful memory means that the normal process of recovering from trauma is very hard. Uchiha simply remain traumatized for far longer and can carry grudges for much longer. Obito was for a good part a traumatized kid, who as an adult was basically suicidal.
