Are these valid Buddha quotes? The BBC has these two quotes attributed to the Buddha that strike me as suspiciously pop-culture-esque assumptions of Buddhism.

Quote #1:    


  An action, even if it brings benefit to oneself, cannot be considered
  a good action if it causes physical and mental pain to another being.   
  
  The Buddha      


Quote #2:    


  If a person foolishly does me wrong, I will return to him
  the protection of my boundless love. The more evil that comes from
  him, the more good will go from me.    
  
  The Buddha


The language isn't right, and they don't stand up to the test of logic.

For example:   

1: A girl pesters a monk to marry her, and is heartbroken when the monk refuses and commits suicide out of heart break. I don't think Buddhism would blame the monk because his intention is not to hurt the girl.     

2: The words "protection of my boundless love" seem odd, when actually per the laws of karma, none can protect another from the effects of their actions. Plus, the Buddha doesn't mind calling a spade a spade - he can't hate anyone obviously, but he isn't going to love the sinners more than the virtuous as the quote implies.
In the first one I think they are summarizing the following from Ambalaṭṭhikā-Rāhulovada Sutta.


  “Whatever action you desire to do with the body [similarly with mind and word] Rāhula, of that
  particular bodily action you should reflect: ‘Now, this action that I
  desire to do with the body—would this, my bodily action, be conducive
  to my own harm, or to the harm of others, or to that of both (myself
  and others)?—Then, unskilful is this bodily action, entailing
  suffering and productive of pain.

The other one seems to be coming from a Mahayana sutta, "Sermon on Abuse" in The sutta of 42 sections


  Buddha said: A man foolishly stating or considering that I do that
  which is not right, will obtain no other refutation from me but that
  which proceeds from the exercise of my four qualities of love (?), so
  the more evil he brings against me, the more good will proceed from
  me; the influence of this resting on me, the effect of that returning
  to him
