What is the ruling on looking at children—without lust—after repenting from pedophilia? Will a person be held accountable for such a gaze, knowing that it does not open the door to committing indecency, and it is difficult to avoid in the workplace?

This disease related to sexual disorders is dangerous, and watching pornography may be an effect of it. It is in itself a reprehensible act and a clear sin. You have been guided to repentance, so praise Allah and ask Him to protect you. Strive for steadfastness and to distance yourself from Satan. Merely looking at children, if not with lust, is not forbidden, though it is better to avoid it if there is no need for it.
