I have death ray and no regrets at all if a few are dazzled. My only aim is to make sure the buggers see me and avoid me.
The problem with this kind of selfish
1 attitude is that it works until everyone else starts doing the same, then you spend more time getting annoying at being dazzled by everyone else.
My problem with dazzling people is that whilst they're dazzled, by definition, they can't see you properly. They may choose to overtake you without being able to see an oncoming car, they then have a choice of a head-on with another motor vehicle, or pulling back into you, and more often than not they'll take the latter option as it results in much less risk of dying than a head on collision with a large mass of metal will.
Obviously it requires someone to try something stupid but, as in most cases, you're unlikely to be taken out by someone who drives within the rules/spirit of the highway code. You're far more likely to be taken out by the person that attempts something stupid (i.e. overtaking when they aren't sure the road ahead is clear).
I choose not to do something that may adversely affect my safety in the future, you obviously do and that is your want. I just think it's a dangerous ploy as you're relying on stupid people not to do the wrong thing.
1. Not a personal attack, but you can't really argue with this.
