Guardian:
你既然都知道，为什么非要一意孤行? so if you know all this, why do you insist on having your own way?
既然你一定要杀一个人，那杀一个年轻的岂不是更好吗, given that you have to kill someone, isn't it better to kill someone young?
地星正直多事之秋, honestly Dixing is troubled just now [多事之秋 doesn't literally have anything to do with autumn, but it's as close as the script gets, and also I like it]

Me:
你既然不爱吃辣，为什么敢点火锅？
秋天比夏天一百倍好。
