This is a very valuable research station. With a nuke aboard it. CC already has knowledge of the Syndicate, and pirates and things of the sort, they know there's going to be a possibility that someone dies. They also know that science expierments could go terribly wrong. Why wouldn't they want to ensure that research is done, and they get their money? If the crew dies, they have nobody to do their research, and they're out of luck. "They'll just hire new people." You might say. But if there are numerous reported deaths there, and their not being cloned, they'll probably go work on some station that does have it. Cause yes, it's not an IC revival, it's a clone. But if something does happen to them, and they die, at least they'll have the clone to take care of their families, get the work done, and keep their legacy going.
I'm also pretty sure he means the number of people that wont join nuke rounds because they're just going to get bombed and die, with no rp-what so ever. You're putting to much faith into the causes of the deaths, thinking they'll all be just.
Deaths are already pretty much permanent. Unless the doctor rushes them to cloning just about immediatley, more likely than not, the person has ghosted and either become ERT/Mouse/Drone. This is also you having to high of hopes for the antags. If they know there's no cloning machine, what's going to stop them from spraying the people down, they're out of the round for half an hour. They'll find some way to justify it OOCly and the person who died is out for half an hour unless they join as ERT/mouse/drone.
To me, it doesn't make IC sense not to have it, and OOCly, just because some people want different rp scenario's doesn't mean a core mechanic should be removed.
