See Definition for kakos { [G2556]}
See Definition for poneros { [G4190]}
See Definition for phaulos { [G5337]}
These words may be used with very little distinction of meaning, but
often the difference is marked. kakos frequently means evil
rather negatively, referring to the absence of the qualities which
constitute a person or thing what it should be or what it claims to
be. It is also used meaning evil in a moral sense. It is a general
antithesis to agathos.
poneros is a word at once stronger and more active, it means
mischief-making, delighting in injury, doing evil to others,
dangerous, destructive. kakos describes the quality according to
its nature, poneros, according to its effects.
phaulos is the bad chiefly as the worthless, the good for
nothing.
