MN 60: Apaṇṇaka Sutta wrote:
Now, householders, of those contemplatives & brahmans who hold this doctrine, hold this view — 'There is nothing given, nothing offered, nothing sacrificed. There is no fruit or result of good or bad actions. There is no this world, no next world, no mother, no father, no spontaneously reborn beings; no brahmans or contemplatives who, faring rightly and practicing rightly, proclaim this world and the next after having directly known and realized it for themselves' — it can be expected that, shunning these three skillful activities — good bodily conduct, good verbal conduct, good mental conduct — they will adopt & practice these three unskillful activities: bad bodily conduct, bad verbal conduct, bad mental conduct. Why is that? Because those venerable contemplatives & brahmans do not see, in unskillful activities, the drawbacks, the degradation, and the defilement; nor in skillful activities the rewards of renunciation, resembling cleansing.

With regard to this, an observant person considers thus: 'If there is no next world, then — with the breakup of the body, after death — this venerable person has made himself safe. But if there is the next world, then this venerable person — on the breakup of the body, after death — will reappear in a plane of deprivation, a bad destination, a lower realm, hell. Even if we didn't speak of the next world, and there weren't the true statement of those venerable contemplatives & brahmans, this venerable person is still criticized in the here-&-now by the observant as a person of bad habits & wrong view: one who holds to a doctrine of non-existence.' If there really is a next world, then this venerable person has made a bad throw twice: in that he is criticized by the observant here-&-now, and in that — with the breakup of the body, after death — he will reappear in a plane of deprivation, a bad destination, a lower realm, hell. Thus this safe-bet teaching, when poorly grasped & poorly adopted by him, covers (only) one side, and leaves behind the possibility of the skillful.
