Well I don't know if Lore had to be trying to take over the whole galaxy to be dangerous. He was very clearly a murderer and had absolutely no regard for life, so that feels like he's pretty dangerous.
Hmm. When would Lore have murdered?
When the colonists died, he wasn't even alive. We have only his word that the deaths should be added to his CV. In "Datalore", he talks a lot and never kills anybody, despite having plenty of potential victims at his supposedly missing mercy. In "Brothers", he again talks of having been a naughty murderer, hinting at having slain the Pakleds who helped him, but we get no proof. And then he attacks his father (well, defends himself from a feeble attack with excessive force), and again fails to kill.
Lore seems to be deeply delusional about a lot of things. Being capable of murder may rank among those - Data has a far greater onscreen tally on taking lives.
I don't feel there is any reason to doubt the story with the Crystalline Entity. Lore didn't have to control it or even hurt the colony himself, but he did lure it there to kill everyone!
Says Lore. But the Entity finds prey without assistance. And when it does, it appears to kill quickly. So how could those kids draw the pretty pictures of it? Seems more likely the Omicron Theta folks with those kids were the ones studying the beast and ultimately sending it towards the colony, which thus had plenty of time to prepare. And the preparations just did nothing for those who stayed, while giving time for Soong to depart.
He was very clearly in communication with it and he was going to lower the shields so it could attack the Enterprise!
And then the shields were lowered to let Lore be beamed out, and the CE just floated there, beduffled, and then flew away...
For all his gloating, Lore again failed to actually achieve
or even attempt anything lethal. Dropping the shields should have been trivial; killing the Crushers, slowly and sadistically if need be, not particularly complicated, either.
With the Borg I feel they clearly said he gave them a purpose and a vision, and that included murder and experimenting on people. That seems pretty awful. Without Lore maybe more of the Borg would've followed Hugh?
Perhaps. But they are Borg...
I feel what was wrong with Lore was his emotions were unbalanced and he was like totally full of what we'd call the "deadly sins": pride, envy, wrath, greed, and so on. So he couldn't handle things and would go to dark places, Dr Soong didn't know how to fix it right away so he had to spend decades working on Data's chip and that's why he was going to give it to him in "Brothers", because he finally finished work on it to his satisfaction.
Seems likely. But having Lore be messed up and having him actually be a murderer are different things, and we probably couldn't go to court with the latter.
I feel also that things like the "dreaming" and such were things that were maybe beyond Dr Soong's abilities, but he put his thoughts in there in case Data ever was able to make the discovery on his own. You saw in "The Offspring" how Lal grew beyond what Data was able to give her, so Dr Soong probably would've known it was possible for the child to exceed the abilities of the parent!
I trust Soongian androids were much more than the sum total of their programming, too. They just wouldn't be that big a deal otherwise.
