Is it true that acting can affect one's behaviour?
For example, if someone plays a protagonist, can this affect them to be a good person? Is there any solid evidence for this?

Also a similair practice can be used for insecure people. If they act confident it has been proven that after some time, they feel more confident as well.
Edit:
Since I'm new to stackexchange I did not know how much detail is desired. Therefore, let me expand upon my original comment.
The article states the following hypotheses:
(1) the actor chosen to play a given character would have personality characteristics similar to that of his or her corresponding character
(2) the actor′s self-perceived personality profile would become more similar to the character′s during the rehearsal and production period.
Later on the article states that:
Support emerged for the second hypothesis, but not for the first. Observations regarding these findings and suggestions for future explorations are given.
The article expands upon this, but I can't access the paper, because it's pay-walled.
