That is a horrific and agonizing death.
Would have been agonizing if she wasn't already dead.
It wasn't a rash decision. I agonized over it.
It must have been an agonizing decision.
All I can do is assure you that I agonized over the decision.
Never knew it was such an agonizing experience.
An insect lacks morality to agonize over.
He won't survive your agonizers much longer.
I have been agonizing over whether or not to say something to you.
I cannot imagine how agonizing this decision must be.
