When alive,we may probably offend some people.However,we must think about whether they are deserved offended.
这全句的主要词在于 deserve 的用法.
按照你的原句子,“they are deserved offended”中,offended 是过去分词做主语补足语.由于deserve 的用法是 “deserve to be done”结构,所以这里的句子改为：“When alive,we may probably offend some people.However,we must think about whether they deserve to be offended.”其他部分无需改动.
