This makes a lot of sense, it's why suicide is a perfectly rational decision. There is nothing to be gained by being alive and there's no real benefit to doing so, it's just fulfilling endless needs and desires, suffering all for no purpose with the chance of things getting worse at any moment, just to die anyway and be forgotten about. Suicide is the best way to die as we will all die anyway, eventually so I see it as being preferable to exit at a time of my own choosing.
Non existence is always preferable to living as it's the absence of everything. If such a thing existed as a positive life experience the non existent would lack the ability to mourn it, but as long as someone exists there is an unlimited potential for pain. To die removes the capacity to suffer so to me it's ideal.
All life is completely unnecessary, there never was a need for life to be a thing in the first place. We were all perfectly fine not existing until we were brought here. Life really is meaningless, and many people live under delusions of life having 'purpose' as the true meaningless nature of life is difficult for them to come to terms with. They don't want to accept how insignificant they really are.
And also I think that worrying about those left behind if we were to ctb is irrational thinking, yet it's so difficult for humans to let go of those thoughts. Whatever happens in life after our death could never be our concern as we simply wont be there to witness it.
