I'll give a yes, she can be as she is rather forgiving and the only time she held a grudge that I recall was against Cinder who killed two friends (though Penny was revived given she was a robot), terrorized an entire kingdom and killed who knows how many which even then Ruby isn't going overboard with it. She'll fight with appropriate measure and outside Grimm, who as Nerd pointed out are literally soulless monsters, avoids trying to kill enemies to where it'd have to be necessary for her to do so.
