I have worked with a few people who blame themselves for every mistake. They often use "I could've done that, I should've known that" or any other phrase in the same line.

This behavior often looks innocent. However, people who use these phrases (blame absorbers) harm the team and the people around them. They create accidental adversaries, and in the long term, they hurt themselves. They miss the big picture and can't see how everything contributes to the mistake.

As I also was a blame absorber in my life before, there are certain things I learned on the way. I wrote about my learnings and how I lead blame absorbers these days.
