If you rape your neighbor's wife, they come after you, too. The fact that you pay the penalty for breaking our legal contract (thou shalt not rape) doesn't make it an acceptable choice for you to make. The fact that the bank can recover some of it's losses doesn't make it right for you to stick them with your losses. When you buy a house, the house is YOURS. It's your purchase, not the bank's purchase. If your purchase doesn't work out to be as profitable as you thought it would be, walking away and sticking the bank with that loss is just unscrupulous. Sure, it's good for you and bad for the bank, but it demonstrates that given the choice, you will do what's good for you instead of what is RIGHT. That's the morality of it. Granted, you can decide not to give a damn about doing the right thing and not care who thinks you're moral or not.... hey, after all, it's good for you and what's good for you is all that really counts, right?
I expect better from my friends, associates and business partners. Anyone that will screw someone else if it profits them is someone I don't want to have anything to do with. I have friends who filed bankruptcy. I don't hold it against them. They tried their best and the debt became so great there was no way they could pay it. The reason I still consider them friends is because they didn't blame the banks or credit card companies or car dealership and never tried so shrug their shoulders and figure it's no sweat. They knew they made mistakes and they knew that now others were going to have to pay for them and there was a sense of remorse. At least they KNEW that it was a failure on their part. At least they know and can acknowledge the difference between right and wrong.
