What were the feelings of McMurdo at the time James Stranger was thrashed, what idea you form about his character?

In Part II, the character of McMurdo is compelling, which is to say before his true identity is revealed. He is bold and courageous, self-assured and arrogant. McGinty sees in him someone he can admire. He does not seem to be afraid of law enforcement, any of the Scowrers, or anyone at the mines. He has little sympathy for those affected by the Scowrers’ violent tactics, though he does stop Baldwin from killing Stanger.
