Same with how Reagan "regretted" things like allowing no fault divorce when if he had thought through all the negatives it would bring and how they outweigh the minuscule positives he would have seen it was going to cause issues and never allowed it. He did it anyway.

Wilson, if he really did say this, wasn't sorry for what he did. He would have done it again because he refused to ever think about the long term consequences of his actions and only cared about the short term gain.
