heres a normal english translation of actII scene I
IAGO
I think Cassio really does love her, and it's perfectly likely that she loves him too. I can't stand the Moor, but I have to admit that he's a reliable, loving, and good-natured man. He'd probably be a good husband to Desdemona. I love her too, not simply out of lust, but also to feed my revenge. I have a feeling the Moor slept with my wife. That thought keeps gnawing at me, eating me up inside. I won't be satisfied until I get even with him, wife for wife. If I can't do that, I can at least make the Moor so jealous that he can't think straight. If that piece of Venetian trash Roderigo can do what I need to carry out my plan, I'll have power over Cassio. I'll say bad things about him to the Moor. I have a feeling Cassio seduced my wife as well. I'll make the Moor thank me, love me, and reward me, even though the joke will be on him the whole time. I've got a good plan, though I haven't worked out the details yet. You can never see the end of an evil plan until the moment comes.
Act 3, scene 3
OTHELLO
This Iago is extremely honest and good, and he knows a lot about human behavior. If it turns out that she really is running around on me, I'll send her away, even though it'll break my heart. Maybe because I'm black, and I don't have nice manners like courtiers do, or because I'm getting old—but that's not much—She's gone, and I've been cheated on. I have no choice but to hate her. Oh what a curse marriage is! We think our beautiful wives belong to us, but their desires are free! I'd rather be a toad in a moldy basement than to have only a part of someone I love, sharing the rest of her with others. This is the plague of important men—our wives betray us more than those of poor men. It's our destiny, like death. We are destined to be betrayed when we are born. Oh, here she comes.
