I think from their perspective Tuvok and Neelix weren’t “dead”, which was why they were more inclined to “correct” the situation at hand and save their crewmates while they still had the chance to do so.

I worked with a startup once where we had individual company emails and had a good giggle at how different the spam is compared to personal stuff! Mostly in our case it was dubious offers of office space, furniture and other such services.
