Than what was the point?Except Culber isn't being killed off. He talks about it on After Trek.
Ever watch "Wynonna Earp"? That was a show that featured two characters who ended up being a gay couple in the form of Nicole Haught and Waverly Earp. When it came time for our heroes to face off against the baddie, Nicole ended up getting shot and everyone believing she was going to die. But she didn't die because unlike how super freaking 'smart' Culber was, Officer Haught was smart enough to be wearing a bullet proof vest at the time. It was a pretty important moment for television when that moment aired because it conveyed how much the showrunners 'care' about their characters. I get none of that with Discovery.
