I'll try and help by reviewing some of your questions and pointing out what might be putting people off from answering them.
Let's start with Why are most interjections a variation of God/Jesus’ name?
It presupposes that most interjections are a variation on God/Jesus' name. This is not true. Starting a question from a false premise makes it difficult to answer.
Perhaps you could try to reformulate your question to ask something regarding the history of blasphemy as an interjection in English.
Next: Words that express surprise disdain anger etc
This question asks for a list of words across a spectrum of emotional states. Such questions are usually off topic as there is no one correct answer. If you were searching for a specific word for use in a specific context then that would be OK.
If you really do want a list, you can consult a thesaurus (for example https://thesaurus.com), and you'll find lists of words that have similar meanings.
Thirdly: How and Why Do Words Change? [deleted]
This is a very broad question, as articulated by John Lawler. This site is not suitable for questions that could take an entire book to answer. Also, the question would be better suited to the http://linguistics.stackexchange.com site, because it applies to all languages, not just English. Although, again, it is too broad for that site to address adequately.
If there is something of more narrow focus about semantic-shift in the English language that you'd like to know, I'm sure we have eager users dying to answer you.
I hope that was helpful.
Finally, some tips on asking questions here:
We really like it when people research their questions and present their findings along with the question. We have a list of commonly available reference works that can help. Also, the question might have already been asked, so be sure to search our archives, just in case.
Keep the question focussed. A question asking for the history of the usage of a word in a given context is fine, but asking for all the different ways a word could be used is far too broad.
Specifically for phrase or word requests: you must at least provide an example sentence. For these types of questions context is everything for getting to the best answer.
