I only think that the people who are screaming when they are about to die are living like a healthy animal. And in the absence of any objective meta-values, it kinda seems like we might well just be what we are.
Denying's one's instincts is an interesting exercise, and no doubt improves self-control -- but it isnt "above being an animal" -- its, at best, a different way of being an animal. One I think, taken to a stocial extreme, seems an injury.
People who readily accept death (as, no doubt, I do) seem injured, and trying to get to this state seems like a kind of self-injury to me -- a means of poking out the eye because the brain doesnt like what it sees.
People screaming when a plane is crashing seem to have their eyes open.
