Personally I don't support Shankar because of his tactics - but I will never make personal attacks at him by calling him cheap/cunning etc. because I don't know the full back story.
What you see on these shows is not a reflection of a persons 'true colours'. Remember the show is meticulously edited and directed - so even casual remarks can be blown up. There are people on this forum who know a lot about reality shows and they say it's all scripted. Also, we as lay people cannot appreciate the level of pressure the captains might be in - they have a reputation to protect after all and so winning is quite important.
My only message is, don't make personal comments because you know nothing about the background of the situation.
