Isnt 'good' ultimately determined by 'what we want'. We organise collectively to determine and label things 'good' that might be in conflict with individual, specific desires. But there must be an ultimate force of desire behind each item labelled 'good'.

Thus said, how does a leader become 'good' without being 'nice'? (Nice having a common starting point of excluding mass murder.) Or shall we say that being an 'authentic' leader does not require being nice? Authentic meaning is problematic, if all terms are purposeful and socially-bound.
