I have not experienced unconditional love. I do not think it is possible in this universe. Evolution favors individual aggression and assertiveness, although cooperation and care can also help make a species or society fitter in the aggregate. And sacrifices of a few can benefit the whole. In the end what counts is propagating genes, and whatever works will win, right or wrong.
I try to be decent in general, yet also have instincts and passions. I prefer to rely on myself, unless I know others can do better, or are the only source. Then I accept help, or pay for it.
I suppose love is different in that it requires no payment. It is a gift with no expectation of return. Yet decency increases the chances.
I love people when it is natural or I feel indebted. But mostly I keep to myself. I like to be honest and when I decide to commit I want to follow through. Yet I also quit when it is too hard. I am only human. I cannot please all, and usually do not feel such an obligation.
