My Chemical Romance - Dead! Lyrics Meaning

"And if your heart stops beating
I'll be here wondering
'Did you get what you deserve?'
The ending of your life

And if you get to heaven
I'll be here waiting, babe
Did you get what you deserve?
The end
And if your life won't wait
Then your heart can't take this

Have you heard the news that you're dead?
No one ever had much nice to say
I think they never liked you anyway
Oh take me from the hospital bed
Wouldn't it be grand?
It ain't exactly what you planned
And wouldn't it be great
If we were dead?
Oh dead

Tongue-tied and oh so squeamish
You never fell in love
Did you get what you deserve?
The ending of your life

And if you get to heaven
I'll be here waiting, babe
Did you get what you deserve?
The end
And if your life won't wait
Then your heart can't take this

Have you heard the news that you're dead?
No one ever had much nice to say
I think they never liked you anyway
Oh take me from the hospital bed
Wouldn't it be grand to take a pistol by the hand?
And wouldn't it be great
If we were dead?

And in my honest observation
During this operation
Found a complication in your heart
So long
'Cause now you've got
Maybe just two weeks to live
Is that the most the both of you can give?"

now apon careful observation of the above, you'll notice that Gerard is indeed talking about ripping into some...insignificant person's heart and finding no spot of love in any of them. And without the love the person is cosidered dead.
As soon as your heart stops beating it means you stopped loving.and it's all simply because you didnt want too love.
you didnt try to love. so you died without love and without a "heart"
