What have we got to fear? When we came to this world, we never intend to go back before we die.
直译：我们有什么可害怕的?当我们来到这个世界上,我们从没打算在死之前回去.
What do we have to be scared of? When we stepped into this world, we never intends to go back.
直译：我们有什么值得去害怕的?当我们踏上这个世界,我们从没打算回去.
不知道是不是楼主要的意思~
希望对你有帮助~
天上~
注：楼上翻译的很有气势,如果改成：Nothing can make us fearful, for we come to this world without a mind to go back 就更好了~
