What should I do if I feel guilty about doing something bad with good intentions?

Due to lack of experience, doing something wrong with kindness will have a certain impact on one's psychology. First of all, you should get out of the psychological shadow and don't blame yourself too much. Things have happened, and no amount of regret can change anything. Turn the page if you can put it down. Let the past be the past. Second, conscientiously sum up experience and lessons, find out the reasons, improve their own abilities and prevent the same mistakes. Learn from your own mistakes and have some experience in turning bad things into good things. Being more experienced than others is also a good promotion for yourself.
