[The Wizard of Oz] If Tin Man didn't have a heart, wouldn't he have been a huge asshole the whole time?

I understand that he was thankful and willing to help Dorothy for reanimating him with the oil but overall he seemed very relaxed and empathetic to her situation.

His problem was not that he lacked the capacity for love, but only that he thought he did. In fact he's quite empathetic from the beginning. Similarly the Scarecrow is insightful and the Cowardly Lion displays great courage. In all three cases, what they really lacked was self esteem.
