To date, The Flashs M.O. has largely been that the bad guys are captured and then placed in a holding cell deep down in S.T.A.R. Labs. Here, though, we seen villain-of-the-week Sand Demon essentially killed by Barry Allen. With the Scarlet Speedster generating lightning, firing it at the rogue and turning him to glass which then proceeded to smash, this certainly seems slightly out of character for The Flash. After all, the group at S.T.A.R. Labs are all highly intelligent sorts and even outlined the plan to turn Sand Demon into glass. Given that Barry knew the consequences of what he was about to do, it just felt a little off to see our hero think nothing of taking the life of his enemy. Additionally, nobody else really seemed all that bothered about this either.
