moral principles and ethics are much more nuanced than you make them out to be. we don't have to go from one extreme to the other and conclude that just because someone isn't totally evil (anti-villains, tragic villains, et cetera) it must mean they're really a naïve little lamb—that's juvenile black-and-white thinking. reality involves shades of grey.
i guess if you look at it from a really broad perspective, then yes, the Master is evil (from a utilitarian point of view—his actions, while not rooted in malice, were ultimately disadvantageous to the human race). but that's missing the point. i made this thread specifically to spark up deeper discussion about his motives/personality. wiseguy "well, duh" replies aren't constructive.
i think everyone is aware that's he's done inexcusable things, no one is debating that. discussing whether or not he was "justified" isn't the point of this discussion—he clearly wasn't, and he breaks down at the fact.
i'm in agreement with you. i think of the later Fallout games as individual entities rather than as a series continuation. Bethesda's imagining of Fallout is so starkly different from where it began, it might as well be an entirely separate game series.
while i enjoyed them on a superficial level, they aren't as weighty as anything in the original. it's like comparing the Iliad to someone's 7th grade fanfiction. they aren't even on the same playing field.
