Devil's Third's Lab Cut Scene
In Devil's Third when Ivan sees that C4 was on the list of those experimented on with the Chimera Virus his reaction is emotional and shoots to kill and destroy the specimens.
Alien Resurrection's Room 1-8
In Alien Resurrection when Ripley discovers the Room named "1-8", she discovers failed clones of herself, and her reaction is emotional and she uses a flame thrower to kill and destroy these clone.
Coincidence or just a plain rip off, I think both were great scenes. In both cases the protagonists' took it personal and as an emotional trigger, also both had their allies watching the break-point and destruction.
