Honestly, I do feel a LITTLE BIT sorry for him. He's just super young and good looking with a bunch of pretty young girls throwing themselves at him, most people would probably indulge,
As far as the leeching and asking for stuff goes, I have mixed feeling. On one hand, it's kinda gross and it's definitely not good to pressure people into buying you expensive things but on the other hand, beautiful women leverage their looks for material gain from men all of the time and if you're a man in the position to do the same thing. why shouldn't he? Plus if the part about his dad making bad investments and losing a bunch of his money is true then I do feel kind of bad for him.
The lying and cheating is still bad no matter how you look at in though and if it's true that he was having unprotecting sex with all these different women then that's just incredibly irresponsible for a number of reason which I'm sure I don't have to list...
