What astonishing reasoning! It is perfectly possible to be a bully and yet not to exemplify the fault of cowardice, just as it is possible for a bully not to be a thief, adulterer or liar. There is no inconsistency in loathing bullies while withholding from them the epithet "coward". "Coward" is not an all-purpose term of abuse for someone who is nasty to others.
