It should be clear from the context of my statement that you quoted that the same result is referring to after death.
Since by the belief of no rebirth, there’s nothing after death, what means is there for further greed or hate to arise as claimed to be the punishment?
Let’s use a very simple worldly situation. A psychopath, incapable of remorse or compassion, robs a bank, goes to hiding in some remote places, escaped the human law, lived out her life in comfort. Vs a devoted Bhikkhuni who trained so much harder than the monks to memorize the Vinaya, trained her whole life, yet not yet enlightened, but had established a super large amount of merits and good basis for the next life’s continued training. According to the belief of nothing after death, these two people will get the same result of nothing after death, making their efforts in this life time meaningless.
If there’s rebirth, then there’s the working of kamma, which is impersonally guiding these two people to two very different places which they start off with very different treasures of their mind and physical situations. It’s not so much punishment vs reward, unless one regard not putting one’s hand into the fire vs putting the hand into the fire as reward and punishment. Kamma is impersonal, it is not God, it doesn’t care about us doing good or bad deeds, it just operates, good gets good, bad gets bad. Like fire burns hands who gets into it, doesn’t burn hands which are wise not to get into it.
Suicidal people wants to die. They don’t believe in rebirth, or temporary forgot that rebirth exist, so they don’t see that death is not the end of their suffering.
I don’t see the relevance of this in context of belief in rebirth. What assumptions are made to produce that statement?
I explained in detailed 2 cases relevant to morality above, for someone who doesn’t believe in kamma and rebirth is more likely to fall trap into.
It’s better to make such statements about the suttas, if you had actually read them all, or at least most of them. I had read the 4 Nikayas, and it’s basically a crazy amount of mental gymnastics to weave them in as you suggested. Or else you’re just not following the Kalama sutta, not seeing the evidence of primary material, preferring to believe in your own pet theory and try to alter the perception of data to fit in your pet theory.
Also useful to read Evolution of Buddhism - Essays - Discuss & Discover (suttacentral.net) There are other teachers who declared no rebirth, no kamma. If Buddha really saw that there rebirth and kamma was not true, he would not have any social pressure to declare it as not true. The fact is he did declared them to be true, by his own direct realization, no less.
