Is it possible that the mes have been tricked into worshipping a demon?

If Jesus isn't the messiah's real name which is Yeshua and the letter J is roughly only five hundred years old, and the Christ walked the earth roughly two thousand years ago, that would lead one to believe that the name is false yes? So if one removes the letter J from the name Jesus and is left with the letters that did exist then, ESUS and that is another name for the god mars what does this say? A well-known section in Lucan's Bellum civile talks about the gory sacrificial offerings proffered to a triad of Celtic deities: Teutates, Hesus (an aspirated form of Esus), and Taranis.[1] Among a pair of later commentators on Lucan's work, one identifies Teutates with Mercury and Esus with Mars. According to the Berne Commentary on Lucan, human victims were sacrificed to Esus by being tied to a tree and flailed. Why is this?
