Stop being so freakin ignorant, it's not because you got pulled over before you killed someone that it couldn't of happened. Yes, it sucks, the person didn't ask to be borned with diabetes, but he/she was! Just get over that and accept it, that person shouldn't be driving if he/she can't keep it under control. It's really that simple... I've looked into (and started) classes to obtain my private pilot's license, however one of the requirement for doing your solo flights is "not to have high blood pressure" Of course, there's a certain range that's considered acceptable... I personally don't fall within that range. What does it mean for me? I'm not going to be allowed to do my solo flights this year, that simple! It's up to me to exercise and to work to lower my blood pressure so I can hopefully start my solo flights next summer, otherwise the one after. If I'm not successful, as much as it sucks, it's very simple: The captain's chair will never be mine. The fact that my blood pressure isn't within the acceptable range doesn't mean I'll have a heart attack, but guess what? They're not willing to take any chances (and I don't blame them, although flying has been a long time dream of mine and it's quite disappointing).
Someone doesn't ask to be borned with a bad vision (some people can actually see, but their vision is so much diminished they're considered legally blind) but even if they didn't ask to be borned this way, if corrective lenses doesn't improve the situation enough so they can be safe on the road (both for themselves and the public), guess what, THEY SHOULDN'T BE DRIVING. Driving isn't a right, it's a privilege.
You seem to have this idea that, if they have good intentions, it's ok. How wrong you are... Someone can have "good intentions" and still end up killing someone. This simply isn't acceptable.
