How do jurors number four and ten make juror five so angry that he clenches his fists in rage?

They accuse Juror ten of changing his vote to Not Guilty.

Brother, you really are somethin'. you sit here vote guilty like the rest of us, then some golden-voiced preacher starts tearing your poor heart out about some underprivileged kid, just couldn't help becoming a murderer, and you change your vote. Well, if that isn't the most sickening - *why don't you drop a quarter in his collection box?*
