Wolverine was caught between trying to respect her autonomy as a person, knowing that she was damaged to the point that she wasn't in a position to make a sound choice, and at the time trying hard to have Scott's back on a lot of hard decisions and sensitive situations. Ultimately, he expressed his views to both Scott and Laura and then said, "Fine. Your life." Which is something Laura has to deal with eventually anyway. Part of making choices for yourself is making bad ones. So maybe Wolverine should get a little flak for not putting his foot down, but ultimately the fault lies with Scott, who should have known better than to ask someone with a history of violence and deference to authority figures. He has to own that one, no outside influence. He may have felt it was the best utilization of limited resources in a desperate time, but Laura should have been confined solely to defending the home base. I also blame Emma. If her vitriolic dislike for Laura hadn't gotten in the way, she might have been very helpful to her as a psychic therapist, and helped her gain enough distance and perspective on her past that she could judge things more objectively.
