Greed itself is unskilful.

Whatever a greedy person fabricates by means of body, speech or intellect, that too is unskilful.

Whatever suffering a greedy person — his mind overcome with greed, his mind consumed — wrongly inflicts on another person through beating or imprisonment or confiscation or placing blame or banishment, [with the thought,] ‘I have power. I want power,’ that too is unskilful.

Thus it is that many evil, unskilful qualities/events — born of greed, caused by greed, originated through greed, conditioned by greed — come into play.

And a person like this is called one who speaks at the wrong time, speaks what is unfactual, speaks what is irrelevant, speaks contrary to the Dharma, speaks contrary to the Vinaya. Why...? Because of having wrongly inflicted suffering on another person through beating or imprisonment or confiscation or placing blame or banishment, [with the thought,] ‘I have power. I want power.’

When told what is factual, he denies it and doesn’t acknowledge it. When told what is unfactual, he doesn’t make an ardent effort to untangle it [to see], ‘This is unfactual. This is baseless.’ That’s why a person like this is called one who speaks at the wrong time, speaks what is unfactual, speaks what is irrelevant, speaks contrary to the Dharma, speaks contrary to the Vinaya.

A person like this — his mind overcome with evil, unskilful qualities born of greed... born of aversion... born of delusion, his mind consumed — dwells in suffering right in the here-and-now — feeling threatened, turbulent, feverish — and at the break-up of the body, after death, can expect a bad destination.

Just as a sal tree, a birch, or an aspen, when smothered and surrounded by three parasitic vines, falls into misfortune and disaster, in the same way, a person like this — his mind overcome with evil, unskilful qualities born of greed... born of aversion... born of delusion, his mind consumed — dwells in suffering right in the here-and-now — feeling threatened, turbulent, feverish — and at the break-up of the body, after death, can expect a bad destination.
