Yeah, it looks like I am using my brain more than some other casual people, hehe...
Anyway, just to annoy you, I'll give you a few more words of wisdom (warning, EXTREMELY long).
Evil can be good.
Think about it. What would this planet be like if there was no evil? If nothing bad was happening? We'd all get bored to death, that's what.
In games, having villians is a good enough excuse to be playing it in the first place. If you actually took the story to be real, it would be you (Mario) trying to beat a villian so he wouldn't rule over the land (Bowser ruling over the Mushroom Kingdom).
But if there was no Bowser, and the land began to prosper, you'd soon be seeing the same thing over and over again. Everyone happy. Nothing new popping up.
So in that case, "Down with Bowser!" at TMK's main page may not be a good idea.
Of course, it would be good, since he's always trying to destroy Mario. For some reason, bad guys continue to try to beat the good even although they will be beaten anyway. But whatever sense it is that makes Bowser keep on attacking, it's a good sense. Then again, if Bowser went out of the picture, someone else would take his place anyway.
One phrase in the game Secret of Mana strongly supports this. The land of Mana is disappearing because they don't take what they have for granted, don't worship it, or whatever. The reason why they don't worship it is because of the land being peaceful. Because of this, the main character pulling out the Mana sword, while causing havoc, was just the thing to solve this problem. A ghost even told the main character it was his destiny, and when you get to the end, you'll realize what he meant.
And think about how it is for the bad guys. They're working just as hard as the good guys. In a way, they're of equal power, no matter what Yoda from Star Wars says. Sure, good always prevails, but think what would happen if evil did win. They'd rule the land, but it would be pretty boring if they killed off all good citizens. Kind of like how if you want to be the devil in Black & White, you need to have slaves. From what we see, evil is always trying to kill or torture good guys. It's actually better in their sense to torture them, though.
We don't have to worry about one side ruling over another, though. If the good side wins, there will always be at least one more evil guy to attempt to cause chaos. If the evil side wins, then there will always be someone brave enough to try to beat them. And since we all know the numbers are millions, we won't be ruled by evil anytime soon, nor will be get rid of our planet's troubles with robbers or other psychos.
Bowser tries so hard to get things to go his way, and it always fails. Yet he's smart enough to keep on trying. That's right, he's smart to do so. We have all seemed to grow up liking or hating Bowser. And I turn out to be one of the people that admires Bowser for some reason (probably this reason), so I don't want anyone complaining about my opinion on the matter.
As for just who you should believe on advice like this, you can't really trust anyone. One point or another in your life, taking advice from someone will fail, but you shouldn't blame them. They all have their beliefs, and no belief is wrong over any other. They all have a reason to think about things. So you might as well decide if I'm of any help to you. Some can be trusted for life, some can betray you. So you have to be careful.
Okay, Mr. Einstein has stopped talking. Tell me what you think of the points I've discussed. And see, it was Mario related, in a way.
PS. I hope to see Yoshi in a 3D GameCube environment soon. That would be so cool!
