There had been murmurings of how much a Lazarus Pit dip takes out of someone, but Thea Queens resurrection only served to further back up those claims. Having been killed by Ras al Ghul in Season 3 and then brought back from the dead courtesy of a quick soak, Thea has whats classed as a blood lust. Whilst thats messed up enough on its own after all, it basically means Thea is cursed with having to kill somebody, anybody, in order to maintain her sanity things take an even more shocking turn when Malcolm Merlyn turns up to offer Thea the names of countless paedophiles and sex offenders. Merlyns logic is that these people wont be missed and deserved to die, and Thea would do well to off these sick puppies in order quench her thirst. To many, Merlyn certainly has a valid point, but Thea is still supposed to be doing the whole hero thing, meaning death to anyone is generally frowned upon. Either way, it was a major surprise to see Merlyn offer up a list of people for the youngest of the Queen clan to kill.
