Okay, I see where you are coming from. The historical discussion of chillul Hashem is what is described in that article. I didnt get that from your statement. More directly it is the Jews not doing what is expected of them in terms of observance...thus reflecting poorly on G-d. Yes, there is a lot of discussions by the sages in that regard. It is a very grave sin. However...chillul Hashem broadly speaking, is anything, that is a desecration of G-ds name...not just by Jews.
But for the sake of argument. Since you are (apparently) attributing kiddush Hashem to Jesus for his martyrdom, the corollary can also exist. From the Jewish point of view, Jesus would be guilty of a chilul Hashem for giving non-Jews the impression that G-d is okay with human sacrifice, violates His own Torah and that makes G-d look bad in the eyes of the gentiles.
... and to demonstrate the impossibility of that which you propose, we return yet again to God's command of Abraham, that he sacrifice his only begotten son. Your logic would have God committing an abomination against Himself, and would render Isaac guilty of chilul Hashem.
For this reason your argument is untenable.
