Nobody can be ideal, everybody got his own backlashes. The person who has blameless character which can be followed by anybody and get goodness only, will be the ideal. Infact nobody on earth is a character whom we can follow and get the goodness only. I can suggest to be like Jesus Christ whose character can generate love only without a flaw of evil. So Jesus is the only person who is ideal. Of course from all the other people we can take good leaving evil, from some one we can take more good and from some other it may be less.
