There are a huge number of lawyers and like any group will contain good and bad people.
The ones I've known - this includes friends from uni who were law students then, through to family lawyers working in child protection areas, to a corporate lawyer a relative married, to my own and exes divorce lawyers and then more family lawyers when ex made malicious ss reports about me, to a criminal lawyer a relative had when falsely accused of assault by a former "friend" and I was supposedly a witness...
All bar 2 were good, decent and professional people who worked damn hard for their clients and didn't as far as I could tell (not being an expert) seek to fleece their clients or in any way act unethically
The 2 I disliked were
My 1st divorce lawyer who was slow, lazy and eventually incompetent. I gave her chance after chance but eventually just went to another firm and lawyer.
My exes last lawyer - he'd gone through a few!
Long drawn out contact issues due to his being an arse. The previous lawyers he'd had dropped him! Which I believe is bloody hard to do but he acted well out of order with them including pinning one up against the wall outside the court when a hearing didn't go his way, he was lucky the lawyer didn't have him arrested!
This last lawyer timed in with my 2nd so we both had new lawyers at the same time. Relatively small town so the lawyers all knew each other and mine when she saw who ex now had just smiled. Apparently this lawyer of his had a temper of her own and was barely clinging on to her own professional credentials. Certainly wasn't regarded with respect within the local legal circles.
It was very interesting watching her and ex interact prior to the hearing and during breaks, as they were losing the head with each other and not quietly! To the point bailiffs came over and told them to calm it down.
This became even more clear as true to me when in court. She kept interrupting the judge, to the point the judge basically had to tell her to calm the hell down! She couldn't control ex (admittedly difficult for anyone but she struggled more than most) and she literally flounced at the end of the hearing slamming the door behind her! Shocking!
But I gather that's pretty rare behaviour and personality for lawyers especially family lawyers.
All the rest I've dealt with were quiet, calm, professional people who spoke in a very considered and measured way, even when I met them socially.
I think people forget that lawyers are as a group responsible for us having laws! Laws which protect and support us and ensure we have the rights we do and to a degree keep govts in line.
I was far older than I should have been when I "clicked" that the reason a lot of politicians studied law or indeed were qualified lawyers because that's how government works - by using laws to set out and control how a country is run.
I've studied it to A-level myself and was vaguely interested in pursuing as a career at that stage but life got in the way to a point, though of course if I'd really wanted to I'd have been more determined.
I also have a relative that's a forensic accountant, same side of the family as the corporate lawyer and they have some interesting debates as of course they're mostly on opposing sides of the type of cases/clients they deal with!
It's all very good natured but they rib each other about their differing viewpoints inc nicknames, corporate lawyer is "plump puss" (ie fat cat) accountant is "goody two shoes party pooper" 
But they do actually get along very well (they have the same taste in music and are both huge fans of a particular band).
I like lawyers they've mostly served me well.
