Is that sort of thing really the right thing to do as a man?
Literal
That-kind [gen-のは] man [as-として] right thing [copula-なんでしょうか].
そういうの 'that kind of (thing)' with の nominalizing そういう into a stand-alone 'one.' として 'as / in the capacity of X' marks a role or standpoint. 正しいこと '(the) right thing' is a stock philosophical-moral phrase. なんでしょうか is the hedged polite question form, softening a moral challenge into a reflective question.
