He literally contributed nothing to that. Any davy that was killed was killed by Garling. What was stopping him from making sure a 3 year old Teach died? He somehow failed that, though it's not shocking when he only decides to DR one person.....which is obviously not a good strategy.
funny how he still wants to sink the entire world, but won't even kill an island full of pirates and rebels.
He also conceded that it was dumb anyway, but there is still no valid reason for him to have left, anyway.
"3 year old Davy clan members? Should be wiped out immediately"
"Island full of pirates to kill? I have to spend more time doing nothing in my castle, anyway!"
There's literally no defending this. By far the worst villain in all of OP, probably even transcends the series in that way
