Regarding your question: "What is the difference between Jagannatha deities and Krishna Murti and why is the latter not fed and cared for as well as the former and why are Jagannathas more tolerant?'' Krishna means Himself and all His expansions, different expansions. So sometimes, Krishna appears as Vasudeva, sometimes as Sankarsana, sometimes as Jagannatha, sometimes as Lord Caitanya, sometimes as Rama, so all such different incarnations includes the Name Krishna.
