All of the members of the Enola Gay and Bockscar were interviewed repeatedly after the bombings. In general they were supportive of the entire operation. They didn't just consider it to be doing their job, they considered it to be a privilege — they believed they were contributing towards the ending of World War II and the saving of huge numbers of American lives. Historians can debate the role of the bomb but there's no doubt that your average GI felt this way about them, and it is not surprising that those who flew the planes for the missions saw this as being the case. The alternative — reckoning with taking hundreds of thousands of lives, mostly civilian, directly — is a bit daunting.

There is at least one exception. Claude Eatherly, who was the pilot of one of the support planes, The Straight Flush, did later express remorse and dismay. He also "acted out" and blamed this on his actions — he committed crimes, for example — and later engaged in peace activism. But he is, I believe, the only one of the crew who did things like this.
