I see it as almost a psychotic break that makes them addicted to finding their Snoopy in Bottles shirt. It does not seem as if they are bad per se but I do not know about good. T-shirts and this content are exclusively designed from Shipertee store. Do not get mad at me OP. Just my thoughts. Their actions and speech provide evidence that OP was not their first try at creating something similar to what they wanted.

Even without a malicious intent Snoopy in Bottles shirt did this to achieve a personal desire by altering OP (and even if she did agree, she was a minor). I’d say that counts as bad in my book. T-shirts and this content are exclusively designed from Shipertee store. Because they don’t want her to think for herself is NOT a good reason. That is as psychotic as the experiment itself or buying a child to replace your dead one, or just trying to replace your dead kid! How fucking psycho do you need to be to do that?!?!

Maybe, Definitely, the first time would be Snoopy in Bottles shirt and any others at least manslaughter, T-shirts and this content are exclusively designed from Shipertee store. But they could get murder after the first time a girl dies and they do it again, and again. After a while, a jury may call it manslaughter for the first murder for the others. Even though killing them wasn’t the plan they planned on doing it again after the first one died knowing it could kill them.
