Arguably worse. If the incentive structure is setup such that (vicious psychopathic) people choose to make this kind of tradeoff, this will just keep happening since the culprit will just be replaced by another link in the same chain with the same motivations. A killer doing it for fun wouldn't have his incentives aligned with the company and wouldn't have all their resources available to hide and facilitate it continuing. Potential killers also know that they wouldn't be able to get away with it for long and would be viciously punished, whereas company leadership know they will be able diffuse responsibility and be minimally punished, if at all.
