I find it quite odd that Michael Clarke Duncan, such a seemingly strong and healthy man, died so suddenly, and shortly after becoming a Vegan. Such a radical change in diet can no doubt have drastic effects on your body, and it's no secret that Vegans often lack many key nutrients like Omega 3. I really think becoming a Vegan is maybe what killed him.

Actually you're wrong. If Duncan was eating a diet full of junk food (meat or no) and switched to being a vegan, it stands to reason that the 50+ years of eating a non-vegan diet contributed to his ill health, not the other way around.
You've yet to come up with a compelling argument to support your wacky theory that a person who is a vegan is some sort of malnourished walking time bomb. I'd ask if you are a physician or even a nutritionist but it's obvious you lack basic common knowledge about how the body works or even an iota of common sense.
Heart attacks can be caused for a variety of reasons none of which are always related to diet. People seem to glob on to a poor diet as being the main cause because we're conditioned to think all people who drop dead must have done something terrible to bring it upon themselves. That something terrible is always blamed on some gluttonous action. Nope and nope.
I'm not a huge fan of veganism myself (mainly due to the fact that the few vegans I've met are fanatical and self righteous which isnt indicative of ALL vegans) but it's certainly not the terrible life choice you're trying to make it. Unless you performed this dude's autopsy and have medical proof that his choice to not eat animal products killed him, save your propaganda and bullsh*t theories for your buddies or your mom. They will surely be impressed with the "facts" you pull out of your a**.
