good question, i asked myself many times:
not sure, what is better, but the real question is: are we all morally entitlet to know the truth ?
I think we all are, but living in an illusion can at times be easier.
However, for me personally, its a 2-edged sword. On the one hand, I feel no more guilt about not doing enough, not being the super-dub like others, about recreational activities, about work-decisions etc.
This is a great relief, I do not regret.
On the other hand, while still in, there are a lot of problems arising, how long can you support something on the outside, while on the inside you are far gone ?
Sometimes I do wish, i never knew.....but its only sometimes...
