A timely murder

Here we are again under the scornful sky
Under the bridge where I watched you die

I'd call it a murder if I'd accept the blame
Even if I pretend nothing remained the same

Take some solace and know I was not alone
The dagger was theirs, though the hand my own

Farewell oh bastard child,
Know that you once were cherished
Farewell my innocent mistake,
Understand why you so timely perished

It was much easier to end you with silent pains
Than to watch you withering in acid rains

Still let it be known this guilt remains shared
The dagger soon forgotten, but one life spared
