There's our difference in experiencing the scene. At the time, I thought he was having a more extreme version of his workout, like he had earlier with the laddies in the bar. I didn't assume that something was wrong but that Lancelot saw the deep-seeded hate within the group and decided they deserved such a harsh punishment. I turned off during the scene, so when the explanation came after, it didn't retro make the scene okay. Had I known towards the beginning of the massacre what was really going on, it certainly would've helped. Instead, I'm looking at the gleefully executed carnage questioning if and why I'm supposed to find it entertaining. Put that exact same scene inside Jackson's lair and make it against his henchmen, it's a totally different experience.
