Are most boyfriends and girlfriends actually safe around a partner’s child?

I would like to think there are more sane partners out there than those "mother's boyfriend or father's girlfriend beat baby/toddler to death" crazy psychos.

Seriously are there still good bfs and gfs that wouldn't harm their partner's child? I know it was the single mother's or single father's fault for bringing a partner home and even leaving their kid alone with them but even hurting someone else's infant (even if it's not your kid) must be sick. Are there still good partners? We always hear news about horrible ones but never the good ones.
