That's the price of your idiocy and stupidity, I'm about to drop.
It would have been much better if the MC had a scar on his eye Kakashi-style, but not blind.
If it was good for human to have one eye he will be born as such. But since humans born with 2 eyes it means that is how it should be. You already lost half of what you was born with due to your own stupidity. And you will never get it back. Think first before doing anything. Think well.
