There's still a lot of unanswered stuff about Prince's death. But I see a lot of people theorizing that Prince died from something that a man of his age, resources, and health shouldn't have succumbed to because the religion he belongs to convinced him that he doesn't need medication (or that modern medicine is the work of the devil or something.)
If that is indeed the case, I feel sorry for Prince. He was taken advantage of. Prince can be considered gullible, but that was not enough to kill himself. Someone took advantage of that gullibility. Lamar Odom, on the other hand, is stupid and harmed himself while being wasteful in the pursuit of pleasure.
Outside of needing a blood transfusion, there's nothing in that religion that would convince him to not seek medical attention for anything that was ailing him.
