if i were to turn my back on joseph, he would have had no one to look up to. i think he would have been dead long ago. >> so you gave him unconditional love? >> yes, i did 100%, and i don't regret it. i loved him with all of my heart and i will love him until the day i die. he was good, and he had a lot of good ways. he just couldn't help -- there was something wrong with his head. >> several times joe roughed up stacy. his mother, pat, would sometimes mediate his arguments with his girlfriends. >> how many times do these girls have to bang their heads against the wall to say, ouch, it hurts. it's obvious, they didn't mind getting beat. they kept coming back for more. you can point at both of them. you can't just point all at joe. remember, it takes two to tango, bottom line. that's how i feel about it. >> carol alexander runs a shelter for battered women in baltimore called the house of ruth. she says that joe's mother played a role in enabling his dangerous behavior.
