What is the purpose of Gandhi's use of hypophora in this excerpt from his "Banaras Hindu University Speech"?

I honor the anarchist for his love of the country. I honor him for his bravery in being willing to die for his country; but I ask him-is killing honorable? Is the dagger of an assassin a fit precursor of an honorable death? I deny it. There is no warrant for such methods in any scriptures. If I found it necessary for the salvation of India that the English should retire, that they should be driven out, I would not hesitate to declare that they would have to go, and I hope I would be prepared to die in defense of that belief. That would, in my opinion, be an honorable death. The bomb-thrower creates secret plots, is afraid to come out into the open, and when caught pays the penalty of misdirected zeal.

Hypophora is a rhetoric device through which the author poses a question before the readers. Gandhi was a great preacher who had a deep influence on his readers. In this excerpt from his "Banaras Hindu University Speech", Gandhi employs hypophora to enforce the readers to think about the actions of anarchists. He asks "Is killing honorable?" and interrogates that how far is it justified and straight away denies it. He replies to this question by negating the efforts of bomb-thrower anarchists that he founds to be 'misdirected zeal'. He indicates the consequences of these actions as they fear to come out in open and suggests rather an alternative to ousting Englishmen if it would be significant to 'salvation of India'.
