Comma necessary?

Hi,

Yankee used this sentence in one of threads. How do we know if we need to put a comma after 'thus'  or not.

To me, the use of 'may' does not rule out the possibility that 'he did that', and thus conflicts with the idea of 'did this instead' at the end of the sentence.

Thank you.

I was asking whether a comma after the word 'thus' is necessary. I have seen with commas and without commas in some sentences I came in contact with and was wondering what the reason mght be. I think 'thus' is an adverb. How about an adverb like "however" or "consequently." If I replaced the "thus" with a previously mentioned word, what would I have to do to figure out whether to place a comma after it.   

Yankee's sentence again with my underlining the part I want to talk about:

To me, the use of 'may' does not rule out the possibility that 'he did that', and thus conflicts with the idea of 'did this instead' at the end of the sentence.

Hi Anon, sorry I missed your "thus." It certainly was clear enough.  (Maybe I'll have to slow down even more.)

I suspect the "Anon" immediately preceding my post is a different Anon, since he said essentially what I said and didn't seem to be aware of the "thus" either.

Another comma after "thus" would unnecessarily interrupt the flow.  Regardless of the word or phrase you substitute, eg, "and in this manner," it belongs with the new action, rather than separating it or introducing it in the manner of a conjunction.  I can't think of a sentence with this particular configuration where a comma after "thus" would help rather than hinder.

If you can come up with one, kindly post it.

Best wishes,  - A.

Edit.  Woops, I'm going too fast again.  You mentioned "consequently" and "however."  And consequently would have basically the same meaning in the sentence as and thus, and would flow nicely. But "and however" as an adverb here is a little strange.  Would you mean in the sense of "and in some way" etc.  ??  If so, I don't see how a comma would help.
