We Christians are suppose to be following Christ, & desiring to be like Him. Having opposite temperament like you expressed, shows a need to get counseling-fast. No way should a Christian act like that to others, & profess themselves to be a Christian. If a person is struggling with their issues, & has a temporary "lapse", it's different, & they probably wouldn't be making a public example of themselves acting un-christian.
Jesus was humble, loving, willing to die for all mankind, & endured the suffering of the cross, for us. The fruits of His Spirit are love, joy, peace, longsuffering, gentleness, goodness, meekness, temperance, & faith.
Having His Spirit in us helps us to have His Nature, but it's a process-life long.
