Is it necessary for fun?

Being homosapien we love to having fun and making fun, but is it necessary to do pranks that makes other feelings hurt. In childhood we did lots of pranks with our old ones and now when we gain a little bit of maturity we feel sorrow on them. We laugh on other's weaknesses and have you ever consider yourself at the place of him whom you making a target. The person may be have obesity, skin problems, blindness, dumbness, physically challenged, deafness or any kind of natural or unfortunate illness but that does not mean that we make fun of them as per their physical appearances. It may be gravel for your eyes to see other people not fit and fine. But its not humanity to make fun of them, to call the person with the problems they had like we all have witnessed the world calling a handicapped person as 'oh pity your life is over'or 'what a curse you got' and on other hand acting their postures to make others laugh. What a shame! A dog too cry when he see someone in pain then why the human emotion get lost away when he saw his own kind with disabilities.
        Fun or masti are terms which means some kind of pleasure to us, or something we do for our entertainment but is it necessary to make other feels down and makes others ashamed for sake of fun? Mimicry of a deaf and dumb person in front of your friends and just for your joy doing pranks with physically challenged person or giving weird, sensitive names to a person due to his/her physical appearances is pretty much normal but have you ever think about the tons of people you hurted due to this tendency. Someone's feelings, someone's emotions and sometimes just for your fun someone loses their life as either they go in deep depression and commit suicide or the hopes of their life drown down and they get shattered.
      In today's our so called photogenic world, first click photos,selfies with the victims and post updates on social media and then after getting hit, think about that how we can help the victim to save their life when its already  too late. Let's put yourself in that scenario and feel how you going to be feel if everyone do the same with you like you did with them. When you meet with any sudden accident and one of your body part get permanently damaged and after sometime when you try to make your life get on path again then some people dominate you on your physical disabilities or if you get any genetical or any kind of birth defect sooner or later in life and your own friends laugh on you for that then what will be your mental status.
  So think twice before making fun of anyone, to judge a person on their physical appearances and  concluding any person as Despicable iff you are human being.
