A lot of innocent Guards were killed by the Suicide Squad
While I like a good caper movie, I was bothered by how many innocent Arkham Guards/Personnel were killed by the Squad.
Yes I understand the Squad are bad guys, but this was a Government Sanctioned Operation. The killings weren't random or accidental, they seemed a planned collateral result of infiltrating Arkham by the Squad.
I doubt even Amanda Waller's "ends justify the means" attitude would have condoned this plan. Even more so, there is no way Batman would not have held her accountable for it. Regardless of her government protection, Batman would have taken her down.
While there is so much of this movie that is done well. This is a disturbing plot point that wasn't necessary to the story. In fact it would have been more interesting if Waller had directed the Squad not to kill at all or literally off with their heads. It would have been interesting to watch the more sane bad guys have to control the baser instincts of their insane comrades.
