Should i be a bad guy?

Hi, i was juz thinking abt something abt my character. I've been puzzled abt this question for a long time. Many ppl think that i'm quite a nice guy, who seldom throw tantrum and scold ppl coz i dun get used to do it. Though it can be something good, but many ppl will see it as a chance to "bully" u, especially when u are a leader or planner of something. When i was ruiying's leader last yr, i'd been thinking abt this. But last yr, as a ruiying's leader, i seldom throw tantrum and scold. If i did, maybe 2-3 times? I admit that my leadership skill is rather avg, maybe i seldom scold ppl and give them pressure. To an extent, it does me good coz ppl are willing to cooperate with me. If we look at it in another point of view, ppl will really bully u. So, i'm thinking, shld i be someone bad and always be someone strict and scold ppl more often? I seldom scold ppl. However, when i scold ppl, i'll be blamed by others like nobody's business coz i dun always do it. Comparing to those who always scold ppl, I'll definitely be a qian gu zui ren and blamed by ppl. Of course in life, it's difficult not to be strict especially when i've lots of chances to be the leader. When i'm simply too nice and perhaps once in a bluemoon, i scold someone, people will change the impression of me in their heart. So, quite confused to choose if i shld be a bad guy?

Then, i dun see that my kindness is repaid and i dun wanna quote any examples. It seems that being myself--- treating other nicely, especially when i deal with ppl who are younger than me(i tend to treat them like my younger siblings, though i dun have any), very few ppl will appreciate. After being so nice to ppl for like days, mths or even years, they say that "Billy, you are juz like any ppl in the world." I totally feel hurt when ppl say that. Though ppl say that being a nice person shld ask any returns, ppl do still hope that your kindness will be rmb by others, right? It seems that most of the time, my kindness is not taken into consideration. Then, by treating others nicely, i'm still not liked by others....

On the other hand, ppl who dun seem to treat everyone nicely and always throw tantrums, are really well-liked and nobody thinks that they are bad. Again, these type of ppl are around us and i dun needa quote any examples.

So, shld i be a bad guy? Coz being nice doesn't seem to be a good way to deal with ppl coz very few ppl will appreciate...
