Why is it that the minute there's an animal mentioned, that the person involved usually becomes an 'animal lover' no matter how crazy their behaviour? This is a person who used stolen cash to buy a dog - and then supported his 'habit' by robbing pet stores. It sounds more like he has issues - and less to do with the fact that he 'loves' animals.
Say you had a person who liked children so much that they decided to go out and say kidnap a few. Would that person described as someone who loves children? Chances are that person would be locked up. When it comes to animals however, any behaviour is explained because the person is an 'animal lover'. It seems that there is a bias that if you like animals then you're probably not too sane to begin with. Tell that to the 71.1 million households that have animals living with them in the US alone - I don't know of an equivalent study in Singapore.
