This is why treasure division must be agreed between players out of character. It can be justified in-character any way they like.
The paladin character would argue that the items are abominations that must be destroyed, not items of value. However the paladin character would also place honour and trust between companions above squabbling over loot, so it cancels out.
As a question of game fairness the paladin's player (and any other players of Good-aligned characters who vote to destroy the items) must pay their fair share for that action in support of their alignment. If everyone in the group agrees that destroying evil items is a contribution to the party's purpose and completion of the mission, then it would be reasonable to deduct their value from the treasure before division.
