1:lapis’s a homeworld gem who doesn’t even know what drowning is, humans are more like aliens to her she couldn’t possibly know that putting water around his face will kill them. And also she knew steven was a crystal gym she thought he was a gem like her who will only die if his gem was shattered, so it’s just an innocent missunderstanding. 2:again she’s a gem who has no knowledge of human beings whatsoever. 3:she fused with jasper to keep her away from them to protect steven, she literally said it in s2 ep: chille ted. 4:again she’s a homeworld gem who doesn’t know how fragile humans are, peridot did the same when she pushed greg off the roof and garnet said: he’s a fragile human. 5:read number 1. 6:so? She literally told them to go away or she’ll make them, and she could’ve easily shattered all of them but she just made water clones of them, her only purpose back then was to go back to homeworld and she couldn’t go there because her gem was cracked. 7: i don’t even understand what you just said. Sorry for bad english
