What is the ruling on a man looking at pictures of girls and women in animated cartoons and electronic games who may be wearing short clothes that reveal their legs and knees, knowing that looking does not arouse lust or lead to temptation?

If anime images arouse instincts and lust, and lead to corruption when viewed, then it is not permissible to look at them. However, if they do not arouse instincts and do not lead to corruption, then looking at them is not forbidden, even though it is better to avoid looking at them altogether.
