Except you can’t delete them. Our deeds, whether good or bad are written down. Records are kept of every action we take. Just like how every website we go to, they send a ‘cookie’ to a temporary folder. The difference is we can delete the internet cookies, but we can’t delete our ‘deeds cookies’.
We can’t eat them either!
(Edit: you can change your deeds, by repenting and doing good deeds to over write the bad deeds. You guys get the point.)
