No, he wanted to kill Nick because of a previous scam. He wanted to kill Judy because she disrespected him by accusing him of having a hand in Otternton's disappearance.

He spared them because Judy saved his daughter, and he happened to grow fond of her overtime. That means he has redeeming qualities, it doesn't excuse his previous acts which were, in all honesty, quite petty and unreasonable.
