It is obvious to care is necessary, it is also obvious, to not care is based on dissociation (for if we fear something, we will dissociate; so, as our sages teach about the bee "neither its sting nor its honey") but caring is an emotion – emotions have no logic – so in order to properly care, one must hand over their brain (for the emotion comes into the brain, but it doesn’t see anything but itself! for example, if someone asks you for money, if your emotion of compassion overtakes you, without thinking you will help; but perhaps the person is a drug-addict and needs to give them food instead – these nuances are so subtle and indeed life/death, that the only person that can discern – God!)
