A man whose wife has just announced that their marriage is over, that she is leaving and taking his 3 beloved children with her. This man, a normally decent individual, is boiling with rage, frustration, humiliation and loss. His life as he sees it is over - pointless. His anger immense
@McRotor96 - Show me where he expressed his rage. The maid has reported nothing by way of domestic disputes. The children are all adults. This was a "drifting apart" of a mature married couple - possibly because he spent more time playing on the SIM setup in the back room, rather than playing with her. So she decided to move out. It was an amicable split.
The Captains closest friend has expressed his opinion that the Captain was a fine, honourable individual, and he would fly anywhere with him. He said nothing about him being a hothead - which he would need to be to fit your scenario.
