He hates his brother's Goldy Pond base. chapter 73 page 1-5

James Ratri
The two of them originally had a good brotherly-bond. Peter even agreed with James his way of thinking for a while because he thought that it was better. This seemed to be a facade when Peter revealed that he was just pretending to agree with James his plans. Peter even went as far to take James his title of the 35th head of the family and claim it himself. He then ordered his underlings and the rest of his clans to kill his own brother, implying the hostility between the two.

Peter seems to have some sort of connection to the demon. Possibly because Peter found out the truth about Goldy Pond that James Ratri made.
