Tilapia kills everything or bullies it to death

I have 3 tilapias (used to have 4, it killed itself, it ran into the wall, don't know why this particular tilapia like to smash into things), i know they are teritorial and do eat dead fish but this is my first time seeing them killing and eating a fish, it was a baby koi fish. I used to grow koi and goldfish together with the tilapias but never seen them killing and eating a fish before. Is it a normal behaviour or something else, when they get bigger will their behaviour become worse and eat all the other smaller fish?

I doubt that some of the users who commented on this topic years ago will answer here. In my work there are tilapia ponds of 4000 liters each, and these guys are really aggressive towards each other, it seems that when they find a weak individual they will chase him to death and eat him, that is the behavior that I have seen in those ponds with these fish.
 
I know, old thread etc, but I just Googled Tilapia and I'm surprised that tilapia is intented for human consuption :eek:
I have had the opportunity to fish it here in the north of Veracruz, near the city of Tuxpan. Although I do not eat fish, but it is very consumed around here.
