He was not killed cause he loved too much, but by the sins of the world. When you say it like that you discredit the whole tale cause the point of the crucification is Christ's glorification, his glory of total knowledge, of being tempted every step of the way yet never giving into temptation. Christ did not hate his torturers, just like the bodhisatvas through time did not hate theirs, because they understand compassion in reality, not theoretically and intelectually. They actually talk the talk and walk the walk--which is the only way of practicing knowledge. Jesus promised more than rainbows, he declared the Kingdom of Heaven exists, that we are children of God, that we shall rest in green pastures, that all things shall be made anew, etc. etc. I dont see how Jiddu's message of us loving eachother differs from jesus' message of us loving and forgiving eachother, not judging our fellow brothers and sisters, and not practicing hate and violence.
