On one hand, we have Freeza deciding to wipe all the saiyans simply because they were getting a bit powerful collectively and Freeza deciding to call the Ginyu force (despite Zarbon's doubts that they were needed) and Freeza proclaiming, almost prophetically, that he had a feeling that they were going to be needed because he had a premonition that a powerful saiyan was developing and that he even doubted that Vegeta was that saiyan. This all paints Freeza as a pragmatic, calculating, take no chances and very aware dictator.ABED wrote: How does that hurt the story?
And then, on the other hand, we have Freeza just going through the motions of the fight, instead of ending it. While his inactivity could be explained by the fact that he had no scouter to hunt his enemies and later by the fact that he was distracted by Guru and Nail, how he acts in the fight is not really consistent. Even if we could explain it by saying that Freeza wanted them to suffer slowly, that excuse doesn't work after Freeza continuously met resistance after resistance and he still only did just the enough to get comfortably ahead, instead of leaving no room for any possible resistance from the start.
The inconsistency hurts the story by virtue of being inconsistent and by making Freeza seem much more stupid than he first appeared to be.
