Even God’s love isn’t, no matter what the religion says. If Jesus can love you unconditionally, then why, according to the Scripture, people who do not accept Christ in their lives would be banished to hell? That’s a condition for Jesus’s otherwise unconditional love, isn’t it? (Am using Christianity as an example only because that’s the only religion have some knowledge of in this context.)
Humans are no better. Blood is thicker than water, but some things neither family nor friend can accept. Like telling your traditional, conservative parents you are a homosexual. Or confessing to your best friend that you once kissed her boyfriend in a drunk stupor.
Everybody is incapable of unconditional love, in self’s opinion.
Those selfless people who fling themselves in front of an oncoming car to save their loved one’s life, they aren’t showing unconditional love. It’s simply a protective instinct triggered. Those wives who accept their husbands’ apology and promise to never be unfaithful again, they aren’t showing unconditional love. It’s a marital strategy to minimise hurt and loss. Mothers who time and again forgive their errant children, they aren’t showing unconditional love. They just have a higher level of tolerance reserved for their offspring; these children’s sins have not gone beyond the limit of their mothers’ conditional love, thus making it seem unconditional.
Love has to be conditional. If love is unconditional, you will love everything and everybody and in time it becomes meaningless. Unconditional love means you are loved without any reason.
Conditional love gives meaning to the people and things you care about. Conditional love sets you apart from the others; conditional love means you can be loved for who you are.
