My memory escapes me sometimes. Has 47 ever been assigned to take out an objectively good person, with no dark underside? Seems like every one of his targets in every game is some type of scumbag. Even Swing King in Blood Money was dealing with gangs and caused several innocent deaths. I suppose a case could be made for Diana, as well, but even she appeared initially to be dealing in something a bit less than on-the-level. But I really don't recall 47 ever having to take out someone really beloved and with no apparent malevolent side. Which, to me, seems antithetical to the idea of an assassin. I think assassin, I think John Wilkes Booth or Lee Harvey Oswald.
Is this just to assuage the player of any sort of potential guilt? How come there's never been a mission where 47 had to, say, take out a beloved politician with lofty goals, and the fee is paid by some scumbag who doesn't want his illegal operations exposed? Amendment XXV in Blood Money was a great level and a great idea, but the VP was still a douche. I'd personally love it if you had to assassinate The President, or someone of that sort of notoriety, who has done no real moral or legal wrong on behalf of someone who is clearly up to no good. 47, at least within the actual assassinations in the games, is essentially a gun for hire who has never truly gotten his hands dirty.
