Seems to me that he would hardly have been able to suck in a lungful of air, let alone make any sort of grand speeches. It seems that some people almost celebrate the awful death of Jesus. He was marched up the hill by a bunch of heavily armed centurions. It's part of The Plan, you see. Maybe it somehow was a selfless sacrifice.
Death is death.
It has never been adequately explained how this death freed us all from sin. Coming back to life after a couple of weeks would have impressed the superstitious locals much more. He must have used his God-Magic to manipulate events and ensure that the crucifixion occurred. This would include making Judas betray him. Either way, he helped the crucifixion take place, so surely christians should admire him.
