I really doubt that most people "idolize" life exactly, they just continue as this existence is all that they know, I mean suicide isn't exactly easy and many likely stay here for the sake of other people. If suicide wasn't so stigmatised and was viewed as a valid option I bet that many people would choose to die if it was straightforward.
But I think that when people force the whole "life is a gift, it gets better" type thing onto other people, it's severe delusion and often I think these types of people are in denial, it's like an illness to me how people glorify life and downplay the true harmful nature of existence where there are endless risks, unlimited potential for suffering, cruelty and torment. Existence really is just an unnecessary harm where all that we are destined for is to decay, it's absurd to me how somebody could see existence as being beneficial, those people clearly lack awareness as existence is way worse than just being futile and worthless, it's something repulsive and causes so much damage. The tragedy lies in the fact that none of this ever needed to exist, yet it does.
