Yes, I believe that an ignorant can do both good and evil, because he does not know and does not understand the meaning of those words. If someone knows what is correct, but still decides to act incorrectly, it is because he does not understand, he does not understand why the right thing is right and why the wrong thing is wrong. He only knows what is good and what is bad, but he does not know why.

All the concepts that we have about good and evil, that we drag from the beginnings of our civilization, have a meaning, they are not there randomly, and if people act immorally voluntarily, it is because he does not know that the actions he is doing, even though they can bring him an immediate benefit, will eventually cause greater damage to him, his descendants, and society as a whole.

The point is not only to know what is good and what is wrong, but to know why that is so, that is what really changes the attitude of people, and prevents someone from voluntarily acting immorally.
