You are putting words in my mouth. i never said they are abusing the nhs merely because they need treatment.
regardless of how someone is presented at a&e/cancer ward/wherever, they will get the best treatment they need. i don't think it's wrong for me to make a judgement on how they got there as long as it doesn't affect how they are treated. i may giggle at child who got his head stuck in railings and i may dispair at the teenage who has been shot but how i treat them will not change.
when i talk of people abusing the nhs, i'm talking about people who miss appointments consistently, who steal equipment, who steal from other patients, who lie to get blue badges, who beat up our staff etc. you can require treatment AND abuse the nhs.
