There are people in the world who don't care about love, and who feel no remorse, empathy or emotional attachment to others. They don't even know what these feeling are. These people are called sociopaths. Most people think of a sociopath as a deranged serial killer, but, with 4% of the population having the character traits of a sociopath, most sociopaths never physically harm anyone. Sociopaths do however ruin lives, empty bank accounts, and cause untold emotional trauma, using simply the fact that they don't care.
