How can i break up this essay question about The Lieutenant?

‘Rooke said nothing more. There was a question forming in the back of his mind, which he did not want to hear. It was: What would I have done in the same place?’
As Rooke struggles with the notion that complicity with violence is as immoral as carrying out the violence oneself, Grenville postulates that individual morality is a superior characteristic than loyalty to country. Discuss.

Above is the essay topic. I am having trouble breaking it down into discussion points. Could you please help me what topics I could base my four paragraphs on? Thanks so much.
