Guilt. A powerful destruction tool. When a person feels deeply guilt, because of internal problems, early life/past lives traumas, or lack of self value and esteem, may unconsciously take actions to further feed the sense of guilt. It's a sort of circle, that sometimes happens.
In case you have made mistakes, that you did not want to do (as you seem regretting that), you can simply start from ground zero with a new account and try to have a better behaviour.
There may be tons of internal problems who lead us to act unwisely, and possibly offend or dispespects others, only because we project on them some of our problems. I think that advanced members, the Clergy, the Gods and wise people here fully understand this so they would not blame you if you "rewind and restart".
Don't feed your guilt, it may insanely grow. If you take positive actions, it should slowly fade away.
