Unconditional love might only exists between a parent and child, due to their biological connection. It of course doesn’t have to exist, just a possibility. Most confuse love as unconditional and don’t think about it. Would you love them if they abused you, if they never said a nice thing about you and tried to kill you? Your love is conditional on them being nice or not trying to kill you. There is nothing wrong with this. Now in this same circumstance many parents still love their mass murdering children or if they have done terrible things, they can’t even explain it themselves but love them.
