I think you may be confusing Hate, with fear. I think when people see homeless or destitute ones, they realize that should something go wrong, they are looking at themselves and they don't like what they are seeing.
A lot of people, in order to cope with their fears about this, figure the poor ones did something wrong, must have made some bad choices or are somehow to blame for their circumstances. Sometimes this is true but often it isn't and to say that it isn't always their own fault, is the same as saying that they too could find themselves in the same circumstances, even though they think they're doing everything right.
JW's view the world as hopelessly lost and irredeemable and the only solution is total destruction and starting all over from scratch. This is a way of copping out...a way of feeling ok about not doing anything to help anyone who is in actual physical need, right now. They even view the support of organizations who help the poor etc, as a waste of time and as useless as putting a band-aid on Cancer, yet in their own time of need, they take full advantage of what the world has to offer.
