Going back to the Torah. When celebrating Passover, and Sukkot amongst other Holy Days the Jews did not give praise to Moses or Arron for their leadership in the Exodus. Instead 100% of their praise was towards G-D.
Martyr means messenger in Greek. This is not about praising Kings as deities but remembering the unjustice they suffered humbly the way Christ did, meeting Him thus in the torment.
