How can evil doers be 'reborn' as 'human'?

In the Pali suttas, SN 56.102-113 state those that realise the Four Noble Truth will be 'reborn in the human state' (*manussesu paccājāyanti*). The same message is found in SN 56.47 & SN 56.48, which also state the human state (*manussattaṃ*) is very rare. As for the law of kamma, the message that unwholesome actions lead to pain & wholesome actions lead to pleasure is found in countless suttas, namely: > *'These beings — who were endowed with **bad conduct** of body, speech & mind, who reviled noble ones, held wrong views and undertook actions > under the influence of wrong views — with the break-up of the body, > after death, have **re-appeared in the plane of deprivation**, the bad > destination, the lower realms, in hell. But these beings — who were > endowed with **good conduct** of body, speech, & mind, who did not revile > noble ones, who held right views and undertook actions under the > influence of right views — with the break-up of the body, after death, > have **re-appeared in the good destinations**, in the heavenly world.*' However, a sutta named the Cula-Kammavibhanga Sutta claims evil-doers can be 'reborn' in the human state, as follows: > *There is the case, student, where a woman or man is a **killer of living beings, brutal, bloody-handed**, given to killing & slaying, > showing no mercy to living beings. Through having adopted & carried > out such actions, on the break-up of the body, after death, he/she > reappears in the plane of deprivation, the bad destination, the lower > realms, hell. If, on the break-up of the body, after death — **instead > of reappearing in the plane of deprivation**, the bad destination, the > lower realms, hell — **he/she comes to the human state**, then he/she is > short-lived wherever reborn. This is the way leading to a short life: > to be a killer of living beings, brutal, bloody-handed, given to > killing & slaying, showing no mercy to living beings.* How can this be? How can one single sutta (Cula-Kammavibhanga Sutta) override the doctrine or law found in all of the suttas that a brutal bloody-handed killer of living beings will experience a state beset by suffering? Surely, a killer than feels no pain from killing & murdering is a psychopath.
