There are times when a person may not remember their actions as they were supposed to be. And there is a really simple explanation for that.
We judge other people by their actions, but we judge ourselves with our intentions.
After all, a person would have no way of knowing what their counterpart is thinking since, in general, they don't possess the powers of mind reading. Therefore, they can only see their actions as reference material.
But is it the same for themselves? What does one think when looking at themselves? How do we judge ourselves? The answer to this question itself is a revelation to the human psyche. Most of the criminals don't think they are criminals at all.
