"The Martian (2015) has quite a Satanic scene where the protagonist cuts up a cross—belongs to a Latino crewman, anti-Catholic—to light a fire and save himself. A religious person would not cut it up, even if it would help him in a utilitarian way; the sacred has its own power."
If burning a holy symbol can keep you alive, you should absolutely do it. In the end it's just a symbol, not the thing itself. If it bothers you, then after you escape the crisis, give back two holy symbols. Can't worship if you're dead. The worshipper is always more valuable than mere tools of worship.
This scene particularly can't be Satanic, because the cross is an implement of torture and death. Symbolically it's the act of destroying and purifying pain and failure to make a safe space for life.
Christianity worshipped the god who died, through the medium of the coward's weapon. They embraced a dishonourable tool as their symbol. It should not be in the least bit surprising that the Christian races treat god as dead and demand their children be tortured before being allowed to join wider society. It is not even slightly dissonant to see Christians enjoying attacking those who can't fight back.
Imagine instead a holy symbol that can not only be burned, but can be eaten. An edible container with bandages and painkillers inside. An entire emergency kit. Worship the god that wants you alive instead of the one that wants you wounded and dying. What a selfish god Yeshua was.
