My account is activated on another ps4 and I want it to be deactivated

[#1]

My ps4 account is on another ps4 and I rather not have it on that account but the person has it activated and I want it deactivated but the person doesn’t want to agree with my terms. So how do I remotely deactivate my ps4 account on his ps4

You'd need to Sign into the Account via Sony App or Web Site and Deactivate ALL Devices..   This can only be done one time in 6 Months.  

Why would you allow someone access to your Account in the first place??

It is against the Terms of Service... and if the intention was to Game Share.. like it sounds like it could be..  then both parties will get banned when discovered by Sony..   and they do monitor their Network..

Never give out the Sign In details..  NEVER.

Also,  add 2 Step Verification and use the Sign Out of All Devices whilst setting it up..  the other person will not be able to Sign back in.
