12 Darkest Star Trek: Voyager Moments Ever

12. Killer Technology - Revulsion

In Revulsion, Voyager responds to a distress call sent by the hologram onboard, finding him alone after the "organics" on his ship died. The hologram, Dejaren, tells the Doctor and B'Elanna that the crew died from a virus, but there is something not quite right about him. The Doctor and B'Elanna begin helping Dejaren to stabilise his matrix, but while doing so he confides in the Doctor his feelings toward organics. And they aren't pleasant.

Turns out Dejaren killed the organics on his ship after he was fed up being a slave to them. The dangers of sentient technology are in focus here, as it was Dejaren's self-awareness that contributed to his actions. It's not just the organics on his ship he finds detestable and he soon shows he is still capable of eliminating others he views as terrible beings, whether they are or not.

Dejaren eventually attempts to kill B'Elanna. Luckily he is unsuccessful, but it's a story highlighting the dark side of technology and why care needs to be taken in the development and use of it.
