Why allspark only create bad transformers?

As title Why all spark only create bad transformers

Well the Autobots were originally made from the all spark.

I think he's talking about when the spark gives its charge to non living things. They go all ballistic and crazy trying to kill. Like the little cell phone in the box from the first one, or the Mountain Dew machine and then all of those things in the kitchen at the beginning of the 2nd movie.

I would say its like that just because they had to create a storyline and a problem. =/

does megan fox's RC decepticon that switched sides count?

i think mountain dew is the most carbonated soda out there...thus its evilness? lol

at least its a good promotion for them cuz you really do notice it

yeh, like how the cube kills and revives Megatron and how Megatron was put to rest in waters so deep, it'd crush anything, yet those deceptatcons were ok.

Hehe, that's what they said in the last movie

Since they all have a sort intelligence and they can reason and CHOOSE what they think and so on, I'd say the allspark creates transformers all alike, and then they choose what side.
Take that cellphone. It's "Born" inside a very tight hostile box. I wouldn't be happy. I'd try to get out, wouldn't you?

But then again, it might just all be random. ^^

In the first film, I believe they said it was the brand of cell phone, Nokia, that made it bad.

Perhaps that plays some relevance to their demeanor when 'sparked'.
