No. The real thing is that two faced people is actually humanity itself. Yes, being human means to care for others and to love unconditionally without any extent of personal matters butremember that human like any other animal has instincts of self defense and versatility which we use to protect ourselves from our insecurities and fears. The only thing wrong with two faced people is that they're so focused amongs themselves that they forgot to fear for rejection thus making them inhuman.
