Situation: You and two other people are in a building. The building is collapsing. Your love's leg is trapped under a fallen piece of rock. It is not that heavy, but heavy enough that she/he requires your assistance. You must help or the building will collapse upon her.
But therre is one other person. This person is in a wheelchair. But, they fell out of it, and it was crushed by a falling pillar.
Less then a minute before the building falls down. The two of them are on opposites sides of the building. There is no way you can save them both. NO WAY!
Guess what most would do? They would unboutedly go for their lover over the other person. But what if your lover is an evil person? And the other person could be called a saint. But you would most likely go for your love over the other person.
So, you would be giving up the life of a good persohn for a bad person. Just because you love her/him. So love is hardly a good thing.
