You have to take the good in consideration, not only the negative, the negative doesn't negate the teaching of Jesus, as the middle way teaches. It's really sad that you just only learned about Siddhartha. I learned about it in 9th grade, reading Herman Hess.
Here's a great Sutra:

Feels intentional to me. In all my years of education they couldn't just squeeze in one little lesson about Buddha?
Thank you for the Sutra!
