I think a "big mistake" is more correct.

Hello,
I was just asked to help evaluate the French translation by comparing it to the English one. But in doing so I was surprised to find that the English translation did not make sense. I don't speak Turkish, but from what I can tell based on the French translation and a Turkish to English dictionary, it should say: "I think that I made a big mistake, and I will pay for it dearly."

"hardly" means "scarcely", "barely", "not much at all". And "compensate", besides requiring the preposition "for", doesn't quite have the right meaning for what was intended.

haha
