Yes and no. It depends on what area of law you go into, who you work for, and how you approach your practice.
Hours: All attorneys work hard. We do often get paid well, but we worked hard to become a lawyer and we work hard to earn it. Most attorneys typically work a minimum 50-hour week, unless they just finished a project or case. Big-firm lawyers can expect to regularly work in excess of 70 hours in a week. Litigators will work 18 hours in a day prepping for trials and hearings, while transactional attorneys can do the same getting a contract, proposal, agreement, or whatever drafted, proofed, and ready to send out the door.
Stress: People rely on you to protect their life, liberty, property, families, or well-being. You know the law and they don't, which puts you in a position of exceptional responsibility. That takes a toll on you, especially when you lose. Often, you're put on difficult deadlines made even harder because clients think they're too busy to provide you with the information you need to help them. Most will lie to your face.
People keep trying to become lawyers because they see people who have been practicing for 20 years at large firms and mistakenly believe they can make that kind of money fresh out of school. They also typically are reasonably smart kids who made stupid decisions on what to major in, and find themselves unemployable after getting a bachelors in some liberal art. Also, law schools lie about employment statistics and lull people into wasting their money on crap educations.
As to ethics, some attorneys are complete mercenaries. Most of us aren't. We are cognizant of our responsibility to the public and try hard to earn the respect our profession deserves. Most of us volunteer our time and donate money to help people in bad situations get right-side up again. I, for one, value my reputation more highly than any form of compensation and strive to give no one any reason to doubt my honesty or integrity. I am a lawyer, and I take ethics seriously, and I have turned clients down because they wanted me to do shady crap I didn't agree with. You always have that option.
