HELL no. What is wrong with you? Not only is it insanely illegal but it is extremely dangerous. Remember that you're not the only person on the road. Don't be a selfish person. If you don't get yourself killed you'll probably get someone else injured or killed and yes you'd definitely be at fault for BACKING UP on the freeway.
