Everyone is mistaken, everyone lives in illusion. At best, we can admit a scale of fictions, a hierarchy of unrealities, giving preference to one rather than to another; but to choose, no, definitely not that...
"You really should come to the house - one of these days we might die without having seen each other again." - "Since we have to die in any case, what's the use of seeing each other again?"
We regret not having the courage to make such and such decision; we regret much more having made one - any one. Better no action than the consequences of an action.
