My interpretation of the song

Hide every thing, keep every secret inside, do not open up your self.

People have to and like to portray only the good side and want you to do the same
Don't leave the keys for every one to see what's inside, most won't believe it.
The ones who care will feel bad, the others will laugh
If you cannot stop doing that, do not bother others with it.

Wake up stupid people, ones who think you are wise and others are not
--Stop creating fables--

I don't think you trust in my self righteous suicide.
But you have to kill trying to find some meaning. That person inside of you
Don't try to break some code or secret of life or stuff like that. They don't want it

Don't try to change everyone, they will do what is making them happy and ignore the rest

It's the way to live today, today Angels deserve to die
The world does not want them
Don't make it complex and think you are simplifying it

It's something that can make you cry when angels deserve to die.
