That wouldn't make any sense at all.

这完全不合情理
It makes sense to be filled with dread or foreboding or what have you only

你感到担忧害怕
if the thing you're looking forward to,

只有当你想到的事情
anticipating, is itself bad.

本身是坏事时才合情理
Maybe, for example,

例如
it makes sense to dread going to the dentist,

你害怕去看牙
if you believe that being at the dentist is a painful, unpleasant experience.

那是因为你相信看牙是件痛苦的事
But if being at the dentist isn't itself unpleasant,

如果看牙本身并不可怕
it doesn't make sense to dread it in anticipation.

那你想到看牙就害怕就不合情理了
So again, if we're thinking about the central badness of death,

所以如果我们想找到死亡的主要坏处
it seems to me that we've got to focus on my being dead.

我们似乎应该关注死亡本身
What is it about my being dead that's bad for me?

是什么使我的死亡如此可怕
