Kinda true. My parent really will have been very well off without me.

The money he pay from pampers till take graduate cert can earn them much better life.

I cannot repay them with what I can earn today. If given a choice I also don't wish to be born. My parent might find happiness in other means.

Your kids are lucky to have such good parent.
Not saying my parent is bad. Is not by any means, I do sometimes think,
My parent can enjoy his life better without me.
