I understand a Messiah Complex as someone believing or stating they were send by God such as most sectarian leaders grouping humans. That is the actual defintion as much as culture is written coltoure or rouge not rogue.
While this is online and in use instead of the definition of normal human behaviour:
If you have a messiah complex, you may feel like you are destined or called to save others. You may feel responsible for helping others. You may have good intentions if you try to come to the rescue (at your expense).
Look. Jesus spoke to you, not us, but you only understood he was rivaling your status. We knew. You had to learn to not live from, but for those you rule. Moses leaded away from you, because you would not even hear, Mohammed showed how to treat you that never stick to their word and live only for themselves. What you think...will Jedi do it all?
