This is, of course, for reasons nobody can adequately respond to with reason instead of feelings, unpopular.
But it's certainly 1. fair and 2. a large cost savings, given the sheer number of Hep C patients who brought it on themselves.
This will not be an issue when the masses that have Hep-C now are cured. This is mostly a short term financing problem. Would you rather solve the issue for $1X now or pay $3-5X over time to deal with it. I would rather cure the masses now and lower the long term medical costs.
The basis is that these people choose, of their own agency, to shoot up with used needles. This isn't some poor guy getting the cancerous genetic bit flipped by a cosmic ray or an uninsured single mom getting disabled by a drunk driver. These are consequences brought on by the patients themselves. By what moral basis should society be paying for the consequences of willful degeneracy?
They certainly chose to shoot up right until the point they achieved chemical addiction, but after that there is much less free will than people presume.

I don't know about you but I hate seeing people self destruct. I certainly feel an obligation to assist them when possible. You might not, but please don't act like your moral compass is the only one that matter.
