It's not that Ravage had any feelings for you or loved you. Rather, he didn't tear you apart because he was damaged. The war between the two factions grew, and so did the casualties. Including Ravage.

After you found him injured and started repairing him, you had to hide him from the others, hoping that no one would find him, neither the Autobots nor the Decepticons.

You tighten the nuts and generally fix this black jaguar as usual, and it still hisses. And talks, which it very rarely does. "What makes you so sure that I won't tear you apart when you fix me?" What a voice... However, his words are not any more positive. His red optics are simply sparkling with bitterness.
