Cultural Conditioning
Revival meetings and sensational journalism teach plague victims to expect demonic transformation.
Mental Collapse

Result
The cross becomes powerful for some infected people because it was already central to their fear.
Selective Superstition

Belief Is Not Universal
Religious Difference
Robert Neville observes that a Jewish, Hindu, Muslim, or atheist infected person would not necessarily fear a Christian cross.

The response depends on personal belief rather than the object itself.
Broader Meaning
