I have huge sympathy for the people who've lost a loved one to drugs, I have huge sympathy for those whose lives are blighted by the wreckage that surrounds junkies - I have no sympathy whatsoever for the people who choose to take illegal (or legal) drugs and then get themselves addicted, they are selfish, greedy idiots.
Saying that nobody chooses to become a junkie is shite- thats the same as saying noone 'chooses' to become a cigarette smoker - of course they do, they CAN stop, any addict CAN stop, its just that its not always easy to do, well - life 'aint always easy, so crack on and stop moping in self pity - the more we feel sorry for someone who chooses to do that with their life, the more they are allowed to wallow in victimhood and not take responsibility for pulling themselves back up out the hole, the best thing we can do as a society is offer them ladders out that hole, not give them methadone to let them stay down there.
In the same way, I have huge sympathy for those who have lost a loved one to mountain biking, parachuting and soldiering - however none whatsoever for the people who chose to take the gamble themselves and lose. If I get killed doing something that I enjoy, I wouldn't want anyone to feel sorry for me, I'd want them to realise that I died doing something I loved, and theres no better way to go! The soldiers I know feel pretty much the same about their own lives, they know the risks, but your hearts go out to the families and kids left behind.
A few years ago, someone I worked with stole certain incredibly strong drugs from work and took them recreationally, her boyfriend OD'd on them and died, very messy all round! Do I feel sympathy for him? not one bit. Should I? No, not one bit, he took it knowing it was a dangerous drug, and he lost. - should I feel sympathy for Katie, a lovely girl, who ended up losing her boyfriend, job, friends and spent a year and a half in the nick, all because she stole drugs from work and gave them to her boyfriend? should I really feel sorry for her? I don't think so, she was a bloody idiot, a nice girl, who did something bloody stupid and paid the price for doing so, sorted herself out and came out a better person for it.
That doesn't mean she's worthless, or a member of the untermensch, but she still has to take the responsibility for her actions.
