What was Malcolms character in act 1 scene 2?

Malcolm is the oldest son of King Duncan. We learn that he has named his oldest son to the next King when he has gone. Malcolm seems fair and humble as he lets the Sargeant and Macbeth take credit for the battle win. This win is the battle where Malcolm was weak and tired and almost overcome.

Shakespeare does not give us any direct character traits we must infer the character traits from the conversation.
