Even he is innocent than he shouldn't be a saint either for saving students. Actually I believe scholars collaborating with KMT/ROC authority that are not trustworthy.
Also, if he was forced to collaborate with KMT, he could be considered "innocent". However, judging from the fact that he "disliked" CCP, I think he might not be innocent as he would be willing to be a collaborator.

PRC搞64，ROC搞46。既然講到了46，複習去年台大：
四六事件發生後，傅斯年對四六事件救援更是保持距離，還主張處分主要幹部。他支持政府掃蕩行動，使台大陷入白色恐怖漩渦中，與外界並無二致。
倒是同溫層有些長輩們反而認為傅斯年是被「表了」：因為他沒想到學生會被失蹤殺害。但我持懷疑態度（理由如連結↑），因為這不改他身為共犯的事實。
