The only part I don't really get is the "You are gambling away his inheritance"...that money was earned by her, not her son...so she should be able to do with it, whatever she wants to. If she happens to gamble it all away, no harm done, I don't see how you could fault her for that. If she decided to spend the rest of her life travelling the world (1st class flights, 5*hotels), her money probably was gone rather quickly too and I guess nobody would blame her for that. But in the end both ways are just entertainment, just depends on the person what he or she enjoys more...
