"An end has a start"

Why is it that so many people hate the end but not the start?

There's a reason for the end, but sometimes no reason for the start. Sometimes the reason doesn't makes sense, but at least it's there, and maybe one day we'll understand. But not today. Not this day. 

I can't remember the start of it, but the end is clear as glass in front me. And clarity is not bad, not bad at all. 

So what's so bad about the end? An end has a start, and can lead to another. Why is that so bad?
