So I won't say just eat it -- but that's what I would do.

Soak in water and vinegar, that will kill off any of the remaining eggs and any bacteria (although it's mostly good bacteria), might not completely remove them, but that ensures that you won't be eating anything other than some shells.

I love kale too, and it can be such a pain to clean, but I tend to wash each leaf individually under running water and set them aside in colander to dry and then remove the spine and chop.. it's a labor of love. I tend to go for broccoli raab now instead since it seems to scratch the same itch as kale for me, and is a much easier clean, boil it for a few minutes in salted water, drain and then saute. It is much faster and easy with higher reward for efforts, and the leaves are just amazing and remind me of kale, a nice bite, some bitterness, and amazing with garlic and butter!

I've just come to the conclusion that it is a pay or play dichotomy. If you don't want to eat bug bits you have to do the work, or pay someone else to, and buy the pre-bagged washed or frozen stuff.

I have a few methods. One if there aren't too many buggers, is just to take a damp paper towel and quickly wipe down the backside of each leaf and then rinse briefly.

The other like CD said, is to soak those leaves in water with vinegar for a while and agitate every few minutes. It gets the grit off too, which will sink to the bottom. I use my salad spinner to make changing the water easier, and do at least two washes. Then you lay them out on a dish or paper towel, flip them over and remove any remaining critter bits with your fingernail, q-tip, or paper towel.

Let them soak for about 20 minutes in warm water. Any bugs will drown and then float to the top of the water. Rinse individual leaves if you have a lot of small bugs like aphids. That's what we did with ours to prep for the Farmer's Market. Now I try to buy from people who make the effort to give me clean vegetables.

If you can get them in your area, switch to collard greens. They have lovely large, thick and SMOOTH leaves that are very easy to clean and even tastier than kale.

My standard cleaning method for greens is to completely immerse them in a sink or large bowlful of water and swish them around. Do that 3 times, changing water in between, with the first immersion in salty water to drive out the critters.

I soaked mine in tepid water and a generous dose of hydrogen peroxide for 20 minutes or so, agitating them once or twice. All the little critters came off, floating in the water and concentrating at the edge of the sink, it was disgusting, there must have been a thousand of them. I rinsed the greens in the other sink, as I usually would, to get any that may have stuck to the leaves due to the soak water being so dense with them. After inspection, I found only a stray one or two that were stuck only by water as they were completely waterlogged and unable to function. I am a raw food juicier and wonder if we miss one here or there and consume it uncooked is there a risk of the insect carrying a pathogen, I.e.:parasite,virus,bacteria,fungus, that could infect us?
