Here's why:
* He ignores warnings: Mr. White is repeatedly warned about the dangers of the monkey's paw, but he dismisses these warnings and disregards the potential consequences of his actions.
* He makes rash decisions: He wishes for 200 pounds without considering the potential downsides. His wish ultimately leads to tragedy.
* He shows poor judgment: He doesn't fully understand the power of the paw and the implications of tampering with fate.
While Mr. White can be seen as naive, curious, and even loving (he wants to help his son), his ultimate downfall is a result of his foolish decisions.
