This was his second visitation. Obviously, he doesn't care about the kids. Further evidence: after he moved out my sister found his web "favorites" were full of incest sites.
My sister is very afraid for her daughter, and is going through hell in letting him take them. Her first attorney's position: "The judge won't care. Most men do it." My sister canned her and got another attorney.
To top it off, he's very active in the church and other organizations.
