No, no one became a HCP to cause suffering.
Yes, the current culture certainly has the potential to cause harm to patients.
Sometimes you absolutely know that what you're doing isn't necessarily in the patient's best interests, but you also know that unless you can be 100% certain that you can without a shadow of doubt both justify, and be supported in taking that off-piste decision, should it not go according to plan, you will be chucked under the bus.
Also, Health Care managers decided to respond the the perceived increase in 'mistakes being covered up' by introducing anonymous 'whistle-blower' availability, and by demanding a 'duty of candour'.

Except what they want is for the HCP to say 'I'm sorry, I messed up, but..'....' thank you, thank you, you can stop there, here's your suspension'.
'...but, if I hadn't been so rushed off my feet in an understaffed and under-skilled department, this may not have happened'...
'Ah, so you admit that you knew you were working unsafely yet carried on? Hmm'
