Death for every person is the end of everything, therefore all religions and most philosophical systems recommend taking care of your own life as the highest value. There will be and there will be no further incarnations - these are fairy tales.
It's easier to live in such fairy tales (hope).
Life can be compared to a field where God or Mother Nature nurtures human minds like plants. In such cultivation, not all minds have an equal opportunity to develop the best qualities of their kind.
Even God or Mother Nature can't help it, or they don't want to change it.
People only have the illusion of faith.
The human body and life are so secured by the survival instinct that achieving one's own death is a very difficult undertaking - AI most often needs a strong impact (invasive methods) - peaceful methods have a very high probability of failure (most often they are effective in the elderly, the weak and the sick) . There is no guarantee that by pursuing CTB instead of 'peace' you will achieve disability (being a plant).
For young people who experience discomfort in life due to a disability in the body or psyche, instead of thinking about CTB, I advise you to focus on what is more possible - improving the comfort and quality of life (the one you have - the next one will not be in any form).
I am not chasing, I am GRAVITY
What belongs to me
Will find me.
