What is interesting about criminal law is to consider what makes something guilty or innocent, as well as to think about what category of crime it belongs to.
ご質問ありがとうございます。
"What is interesting about criminal law is"＝「刑法の面白いところとは」
"is to consider what makes something guilty or innocent"＝「何が有罪で何が無罪なのかと検討すること」
"as well as to think about what category of crime it belongs to."＝「そして、（その）罪がどの種類に当てはまるのかについて考えることです。」
ご参考になると良いです！
