Temptations

The devil visited a lawyer's office and made him an offer.
- I can arrange some things for you, the devil said.
I'll increase your income five-fold. Your partners will love you; your clients will respect you; you'll have three months of vacation each year.
All I require in return is that your wife's soul, your children's souls, and their children's souls rot in hell for eternity.
The lawyer thought for a moment.
- What's the catch ?
