I've found that if the parent uses the stricter punishment, that it will show up in the child's relationship panel. For example: I had a toddler sim who would autonomously make messes. All. The. Time. To which I had my parent sim (their dad) punish them for - usually strictly, like with a time out or a 'talking to'. Now, when looking at the child's relationship panel with said parent, I believe it said something along the lines of "happy childhood, with some rules" or something like that; I'd show a screenshot, but said child has been aged up and no longer is alive.
I've also found that, when a child is punished strictly/harshly a lot, the relationship panel will show it when they age up. I've also had it say something like "bad childhood, bad relationship". Again, I'd share screenshots, but I'm not on the computer that has the Sims 4 on it (however, if you're still interested in me sharing them, I can post them tomorrow).
I'm not sure how much it affects their character values, though. I don't think parents can encourage poor behavior - unless its through the teaching motives. I can't say I've ever tried it, though, so maybe it is possible.
Maybe if the parent is 'evil' or has the bad manners trait? I've never allowed that to happen to my Sims, so I can't say if they'd be able to influence the kid in a negative way.
Toddlers, kids and teens do get a boost to some of the positive traits when they are disciplined, but it might depend on how. I haven't really experimented much, since I have autonomy off and my kids don't make messes, etc unless I tell them to. About the only opportunity I have to discipline is when toddlers refuse to take a bath, and I've noticed that a 'firm' response gives the tot a bit of empathy. (Unfortunately, you can't discipline them for throwing food in the high chair, and I've been complaining for ages that parents can't do anything to get a kid or teen past the loud and obnoxious phase.)
