Trump may very well be changed by the responsibilities of the office of President, and he will grow into the job.  Maybe his ego will make him want to be loved by everyone, and he will act accordingly, although that is unlikely with the advisors he is gathering around himself.  But it is absolutely certain that the hatred he sowed among his supporters during the campaign will continue to grow.  It has already begun with the celebrations in many rural areas, the attacks on Blacks and Latinos, and the rhetoric shouted on the street.
