4. I'm a little confused

Your MIL can enter the US for a long term stay, it seems.

Your FIL may not be able to, but he's going to be in jail for 3-5 years in China, so a US visa hardly matters at this time.

Is the problem his wife wants to stay in China to visit him periodically?

I think you have no problem except helping your wife and MIL emotionally. You have 3-5 years to talk to an immigration attorney and see if they let in a person convicted of a felony.

As to visits by your wife and MIL to him, be sure to check out how leaving the US temporarily affects visas. I believe there are some restrictions on that that may invalidate the visas.

Your FIL has trashed his family, but there seems to be no way you can fix that for 3-5 years. Unless you can buy his way out of the conviction. But be careful there as well, that may be considered illegal in the US.
