You owe it to yourself to make double repentance: first on behalf of yourself and second on behalf of the person you have forced to sin.

 

Even as a person who inspires and sets a good example is rewarded doubly, a person who misleads and compels people sin would also earn double punishment. Allah says:

 

“[And God] will say: “Join those hosts of invisible beings and humans who have gone before you into the fire!” [And] every time a host enters [the fire], it will curse its fellow-host -so much so that, when they all shall have passed into it, one after another, the last of them will speak [thus] of the first of them:  “O our Sustainer! It is they who have led us astray: give, them, therefore, double suffering through fire!” He, will reply: “Every one of you deserves double suffering -but you know it not.” (Al-A`raf 7:38)

 

Almighty Allah knows best.
