Doctor Who Flatline and Self Evaluation
This is a great scene not only because it’s important to the character development in the series, it also covers an important point in self evaluation. The Doctor is being confronted with his own behavior by seeing himself through the behavior of others. Clara is happy that the day was saved even though people died. And the Doctor knows that this is not a good thing - neither for himself nor for Clara.
And in general, people are terrible at self evaluation. We strongly tend to be our own worst critics. Or we don’t recognize patterns of behavior that need to change. In the case of a negative behavior pattern, it’s easier to recognize that pattern in others and then ask ourselves if we behave that way. Or in the case of self-criticism, here in the Tumblrverse, you will see many who are unhappy with their face, body, or hair because they think it makes them unattractive. But if they were to look around, they would see plenty of other people with physical attributes not so different from their own who are perceived as attractive. And perhaps this will lead to the realization that they are much more attractive than they currently believe.
