I did not say that it's a good reason to kill for your job because you could also take another one. But they do it because they want to take this job for whatever reason such as revenge, to protect humanity etc. (That probably doesn't apply to Arima, though)

Well, we don't know for sure but there are clues that suggest that. Like Hairu's flashback that implies that Arima was also part of the Sunlit Garden. And we can assume that it's pretty fucked up there from the hints and people that come from there. Or that Arima has already been an Investigator as a teenager. And that he never knows what to write in his testament and always delivers a blank paper.
