It's definitely putting the "second" company at a loss, since staffing is not nearly as easy a task as is saying "I accept."
Honestly, think about the "second" offer as a legit job and consider whether you'd really want to work there. If yes, accept the offer. You will have many jobs throughout your career, some more fulfilling than others, and they all add up to your career—the sum total of your experience.
If you really want the second job, go for it, and leave the other job by the wayside. Having worked in jobs that, in hindsight, I hated, I can say it's not worth it to work at a job you hate (or even mildly dislike).
What is good is good work. Pick whichever job you want to go for, and do it. Even though it's hard for a business to staff up, it's a business, and business is business. You are a person, and your life is your life.
On the financial end of it, don't worry about that either. Money comes, money goes. Having been in the workforce for nearly 20 years, I can tell you that job A will not directly affect you except in your ability to negotiate further. That being said, you can always negotiate further—your future employers will not have direct access to your financial situation, so you will still be at liberty to play poker, as it were.
THAT being said, money doesn't matter as much as job satisfaction. Would you murder innocents for six figures? Bottom line, don't waste your time doing anything you don't enjoy. The money will come.
