Best Thanos Taunt in Infinity War

All that for a drop of blood?

You should’ve gone for the head.

He was taunting Tony.

He was almost sad that Thor missed. No taunting at all.

Nebula : I didn't feel much emotion on this scene

His Tony taunt cuz Tony really went for it. Thor was misguided and wanted to make Thanos suffer.

"You should've gone for the head."

Should have gone for the head was more powerful however “All that for a drop of blood” really paints a picture for how feeble it was to try and stop Thanos.

Not a taunt but I loved “I will bathe the starways in your Blood”
