Should've Known Better lyrics

I lost my love, I lost my inspiration.
It was right in front of me.
My every thought, my every incarnation
Is to stop a killing spree, but my self-esteem and confidence were lost along the way.
Should've known better.

I should have known. Should have known. Should have known. Should have known.
[ Lyrics from: http://www.lyricsmode.com/lyrics/d/darkbuster/shouldve_known_better.html ]
There was a will, there was a way to always make it better
Before it all went black. And that's ok.
You're a shamrock wearing devil
I'm gonna violently attack.
You're a nay sayer and a ne'er do well threaten me with harm.
Should've known better.

I should have known. Should have known. Should have known. Should have known.
