Different circumstances, completely. Or are you suggesting Lara specifically aimed to get Luke in the gladiator chamber with her so as to have a go at him?

While the votes are also responsible for what happened in that situation, I wouldn't say he is blameless, either. What would I do? Perhaps the same. Does not change that he actually did it, however. Knowingly, and with the intent to escape the-- however twisted and disgusting-- punishment for being staff.
