4. Dragon Age 2 - Anders blows up a chantry
We knew BioWare were going to be on this list. They are after all fuelled by fans tears.
Towards the closing moments of Dragon Age 2, Anders sends the player to collect a selection of items he claims are to aid him in ridding himself of an evil spirit that
lives inside of him feeds off him,
By the time we learn of Anders' and Justice's plan, it's too late to do anything.
Every item you've been collecting to “help” him, is actually the components of a makeshift bomb. A bomb that he then uses to blow up a chantry, the Dragon Age equivalent of a church.
Anders blowing up a holy building is a hard pill to swallow and is the ultimate betrayal. He tricked the player into helping him, and used us to accomplish a goal to further his own ambitions regarding the treatment of mages.
What makes this scene so excruciating to watch is what follows. The repercussions of Anders' actions are decided by the player. We decide his fate. Do we let him off, despite blowing up a holy building and murdering it's leader, just because he's our friend? Or do we do the right thing and execute him there and then so that “justice” prevails?
Still to this day, I don't know if I made the right call.
