Help with rewording this sentence?

Question

(Introduction)

Tim O'Brien was a coward, but not any ordinary coward. He was a coward for going to war. Why is he a coward to go to war. Tim O'Brien may thought he was a coward because of embarrassment, fear, or possibly mockery.

(conclusion)

[[The embarrassment, the shame, and the mockery were the three components that did not let O'brien escape to Canada.]] He served in the war, not because he was courageous and brave. [Tim O'Brien went to war because he was afraid of embarrassment, shame, and mockery.]

The double brackets [[ and the single brackets [ are repetitive. I don't know how to fix it without loosing the tie with the intro.

I think the best way to fix is to change the double bracket sentence but i stumped on what to change it to.

How do i fix this? Also how does the intro sound?

Answer 1

How about this?....... Tim O'Brien had gone to war , not because he wanted to  , but because he feared the shame  and humiliation of being labeled coward and gutless worse than combat itself....
