I use if I want to........when I want to...
If the actions of my enemy have earned my respect I will sometimes I have the odds stacked on my side some times not............ its his actions I consider........not my own.
If you finish off someone who is low and slow and has fought well why not salute him................ he did well but fell to the inevitable.
If we use as some sort of mutual back slapping ritual (always expecting one back) then it loses its meaning IMO ..............
and when there is little else to do and no good fights to be found then cherry picking can be fun for a little while
