and for what reason did he

I'm sorry, but only unconditional love can be considered Christian love. You can make the case for tough love, but that's only rationalization. Love doesn't come with strings, ever. You can even paint the picture of love seen in the bigger picture of the larger whole, still not love for that one-on-one. I've got plenty of examples in my own life showing I'm no expert on love, conditional or otherwise, but I'm not the one making the claims of love. To stand there and say that being taken advantage of is not the intended Christian way is a means of perhaps easing your conscience. But please don't defend this in the light of love. Christ knows no condition.
