What character traits do macbeth's exploits on the battlefield demonstrate

Through the Captain’s tale of Macbeth’s feats in Scene 2 of Act 1, Macbeth is presented as afearless and loyal warrior who would die for his king and do everything in his power to protecthis kingdom; a noble man with the strength of ten men and the morals to match. However, thescheme that he hatches with his wife is one of a snake and a coward. Rather than beingoverjoyed by the king’s generous rewards, his trust and his offer of friendship, Macbeth secretlyplots to murder him and steal the throne. Moreover, rather than face the king directly, Macbethplots to commit the crime while the king is defenseless - sleeping in his bed - and place the blame on his servants.
