Well he obviously didn't "make the church" as none of those organisations came into existence until long after he was dead. He set forward ideas on how people should live and treat others which pretty much all those organisations have largely ignored.
Plus your missing my key point. As you say they have power structures and interests. The issue is that those interests are the ones of the people in charge of the relevant organisations. Chiefly on maintaining and expanding the power of that organisation and their own personal position. Which often has not matched with the ideas Jesus is reported as proposing in the bible.
1 & 5 I follow the evidence.
2 - actually it needs ideas on what is good. That can change over time for various reasons. For instance finding genocidal war, slavery, serfdom, sexual and other bigot no longer acceptable. However the decision on what's good needs to be decided by reasoned debate not dictate from on high related to power politics.
3 - Jesus's message is about how to live. It did not include complex dogma and unquestioning obedience to people who set themselves up as demi-gods to dictate how others should behave. He objected to that in 1st century Palestine and would I suspect similarly object to assorted bureaucracies in the established churches today. Assuming god exists and wishes to control his creations that greatly its for him to decide what is the correct path [or paths] to salvation not a group of self appointed functionaries who's main interest is in power. You yourself have admitted the higher levels of the Catholic church have been corrupted in at least two cases after all.
4 - That is your opinion and the case stated by the very establishments which parallel those Jesus opposed in his own time. All religious establishments have claimed to be divinely inspired throughout history. Nothing new there just as nothing new in them becoming corrupt and often parasitical.
Plus its odd that you say equate Jesus with god and that he/they created the church when you yourself argued he never claimed to be the son of god?
