Re: Superheroes Who Kill?
If you want to run a 4-color CVK game, you have to make sure that the players know this, and know to make appropriate characters.
For the CVK campaign, a several character concepts just won't work. The ex-soldier, for example, has been trained to kill threats. Cops won't hesitate to use lethal force when a life is on the line ( I know a couple; when it comes down to 'us or them', they are trained to shoot ).
The CVK superhero is almost always someone with a regular life who somehow gets superpowers. They are raised by their parents and their society to equate killing with wrongness. (Which, incidentally, explains why a lot of people are uneasy around cops nowadays, much less sodiers. Sure, we support our troops - from a distance.)
It is my personal, firm belief that there are some (granted, only a very small number) people who need to die. I would prefer that they be taken in, given their day in court so people can be shown why they need to die, but if they have a gun to a hostages' head, I want the police sniper to take the shot. Better that then let a killer escape to kill again.
In game, this can become an issue. I have played a casual killer in game (and come to regret it). Now I tend to play cops/solider types. For these characters, lethal force has its place. It's not the perfect solution to all problems - violence rarely is - but sometimes it is better than the alternatives.
