"I could just... Blow it up...?" Joseph Carson mutter to himself, pacing about as the protest continued. He then shook his head. That would be far too easy, and he couldn't get to see the look in Bruce's eyes as he broke the man and relinquished control of Wayne Enterprises to him mere moments before his death. 
And all Bruce would see was a well polished red helmet. While he would be torturing Bruce, Joseph wouldn't even allow him clothes. He would give the rich man nothing, just like Bruce gave nothing to the poor. He would be in the same room filled with one way mirrors facing inward. 
People could walk about and watch as Bruce Wayne was tortured to death, day after day, and all Bruce would be able to see was his own horrid reflection., decaying further and further with each dreadful passing day. He wouldn't even be able to recognize himself after a few days, and he would never be the same person again.
 He'd get two meals a day. Soft foods. No utensils, no plates. After all, he needed his favorite torture doll to be at his best, so he could give out his best screams. 
Ear-shattering. Dripping with desperation. Begging to be freed. And finally. That one day would come. The Red Hood would give Bruce only a paper and Pen, allowing him to sign over everything he had and in turn be freed. Bruce would sign that paper with that pen. And then that Pen would find it's way into his head through the eye socket. Bruce will be free from torture. The Red Hood will own Gotham.
