Prophets are high valued people used by religions around the world, like Jesus, Mohammed, Bhuda, high respected personalities like Japanese Emperors, Ethiopian Emperors and other minor characters. Do you think it's right to mock Jesus the way people do? Or to use him as a character, souvenir or picture to be used anyway you want? Do you also think it's okay when people kill a lot because they felt offended seeing their prophet?
there are some points I see.
first is to mock a high-value figure?
the second is an important character in the form of a prophet or a figure of high appreciation that is used as a souvenir or picture?
the third is killing for the offended reason to see the priest being cherished
okay we discussed the first one, right not? the mocking act is a negative thing and it's an untruthful act, and obviously that's something we should avoid
the second is dependent perception of each, there is a perspective to make drawings or make souvenirs in use to get closer to his God. there is also a supposing it should not be for some reason, just how you respond.
the third is there are some circles who do not allow to show the form of prophet, then there is a picture of the prophet and kill him. it is clear that the act of killing is not recommended in all religions, there are still many ways to reprove it without having to kill.
that's my view on your case
