I would expect the wizards player to play a bit more in Line with his Int, and both PCs could be expecting a long and serious spiritual and moral check and lecture at the next main temple of the pallys church.
Every Pally ho didn`t nothing against the selling of an evil item would be an Ex Pally.
If the spellbook was evil, or hold only/mostly evil spells then I see nothing wrong with destrying it.
Lawful:
The only Laws here concerning are his code and the tenets of his god, faith and church.
The PCs should also remember, that being allies, comrade in arms of a pally could have his own advantages.
Like a better reputation, help from the church and so on.
