IPC aur BNS mein ACTUAL fark hai kya?

Maine IPC ka chapter 87 read kiya, "Acts done in good faith for the benefit of a person without his knowledge or consent" ka. Phir maine BNS ka chapter 33 read kiya, "Wrongful act to deprive any person of his property". Ye dono chapter ki section ki kahaani ek jaisi lagti hai. Kisi person ke baare me janta bina karke kuchh karna ya kisi person ke property ko chorrna, dono hi kuchh jaisa hi hai. Par kya IPC aur BNS mein koi actual fark hai? Kya main wrong laagta hoon? Koi bata sakta hai kya.
