It's difficult to comment fairly, as the article doesn't state his relationship to the victim, but people who engage in bareback sex must take a degree of personal responsibility if they pick up a disease like HIV.
If the victim is somebody who had sex with him outside of a longterm, trusting relationship then she's likely to be partly at fault.
This guy is clearly scum but we all know the risks that somebody we have sex with might carry the virus, knowingly or unknowingly. The article states 'even though she is not at fault for it'. This may not be entirely true.
Take responsibilty for yourself and this won't won't happen!
I would of course agree that this is tragic if the victim is in fact his wife. Also 2 1/2 years is not enough for him, regardless of the victim.
