Do you think this quote is true?

Question

"No matter what anyone says, no matter the excuse or explanation, whatever a person does in the end is what they intended to do all along."

~ quote by Cus D'Amato.

Answer 1

Well it's got a lot of explaining power, hasn't it? 

If they didn't intend it, why did they do it? Especially if it's offensive, and they've been told over and over again, and they just keep doing it? 

Answer 2

this is not true at all. people make mistakes and do things unintentionally.
