An audio recording of the actor losing his temper with a crew member was leaked online in February, creating a media storm.
Bale later made a public apology for his behaviour, admitting that he had "acted like a punk" and was "out of order beyond belief".
Reflecting on the row in a new interview with Access Hollywood, he commented: "You think about the numbers of days we shot on that movie - 77 days - everything going well. What's being focused on is four minutes where I behaved bad.
"I didn't want that to overshadow the hard work of everybody on the crew, in every aspect. So I felt like I had to say something."
Asked whether the incident affected his popularity, Bale replied: "I don't even think about that. I don't really have an awareness of what anybody's perception of me is, I don't like to. I like being oblivious to that because it allows me just to get on with whatever project I'm doing."
Terminator Salvation is released on June 3 in the UK.
