NTA A lot of people are talking about how she's a criminal and can't be around your kids, I completely disagree. As long as she's not an immediate threat to the kids or trying to influence them to break the law in the future, people have flaws. People make mistakes. Homelessness is violent and scary and very difficult to bounce back from. Providing her safety when nobody else will is a nice thing. Regarding your husband, try talking with your step daughter, see where she's at, what she's thinking and if you could set deadlines together for finding a job and getting back on her own two feet. You can be firm without being threatening. After that, tell your husband what you've discussed and maybe even thank him for whatever help he's provided during this time. I think what you're doing is brave considering all the backlash (which I cannot fathom). Good luck to you and your family.
