Well, I may have word it wrong about Erza Knightwalker, she may have enjoyed it, but like you said she had to be taught the importance of life.

I do not believe that "Strength of Feelings" can justify killing, pillaging, loathing others all for the way they feel/loyalty towards their masters. And your real life examples of suicide bombers really coincide with the Juvia vs Meredy fight because she was willing to kill herself for her "mother" just to take down Gray and Juvia all because she "loves" Ultear, that is not love, that is idealization blindly toward someone without question, it is until the end of the fight that she truly understood what it means to love someone, they must live for them or else it has no meaning, even her magic transcended sensation to emotions. That is the true meaning of "Strength of Feelings" or in other cases "Power of Life". Or in the words of Erza Scarlet "You don't die for your friends, you live for them."
