What is the single most important role of a parent?

parenting involves a lot of different roles...we are not just mother/father we are, counselor,friend, healer, teacher, financer, home maker, skills trainer etc...u name it and parents r one who have done it first...so I find it difficult to say which is most important role....it's more of a lifetime journey. we play our roles so well that even movie stars are outshined by what we can achieve... so I guess the answer to ur question is parenting...that's the single most important role
