You will get the most common conclusions and solutions here. I am not a Guru or someone special but I do find myself most of the times in situations where my judgement becomes universal.
Well I wont call myself a critic or a judge of the human behaviour but it is not wrong to oppose what is wrong according to you. You have the right to express yourself so why not use that right for some purpose. To survive in this world you really don't need anyone to be with you, we make ourselves weak by being with someone. We prefer to be weak when at the very same time we can be the strongest.
