Don't watch Evangelion for Kawoshin.
It's a perfectly great show on its own with/without that.
Sephirotic's release is generally considered to be the best: https://nyaa.si/view/831686
If you must, you can watch it on Netflix. Their translation doesn't really tone anything down, it just lessens the impact of some scenes due to its more literal translation.
Watch order: NGE episodes 1-26 (Make sure you're watching the Director's Cut versions for episodes 20-24)
Then you can go on to the movie End of Evangelion. Death and Rebirth is just a recap for fans who have already watched the show.\
If you still want more Eva after all this, you can move onto the Rebuild moves - there's currently three that have been released and the final one is set for next year. But don't expect much, it's inferior to NGE/EoE in every single way.
