About "tadashii", present or past

Question

It's the literal translation of this line

お前を正しいと受け入れていた俺の心が弱かった
omae o tadashii to ukeireteita ore no kokoro ga yowakatta

"My heart was weak because accept that you are right" or "My heart was weak because accepted that you were right?" I understand that "tadashii" word it's in present form, past form it's "tadashii katta", right? Or there are any way to that word can be in past form in this line without change it?

It's the line in 28:59 to 29:04 in this video. youtube.com/watch?v=8o01LRQx7wM&t=366s Don't look the subtitules please.

Answer 1

Japanese is just like algebra:
The past tense (present tense A + present tense B)= past tense A + past tense B

I'll show you an example: 当時｛とうじ｝、お前｛まえ｝が好｛す｝きだと俺｛おれ｝は思｛おも｝っていた。
I thought I loved you in those days.

Is the 正しい a present form in "お前を正しいと受け入れていた俺の心が弱かった"?
Is the 好きだ a present form in "当時｛とうじ｝、お前｛まえ｝が好｛す｝きだと俺｛おれ｝は思｛おも｝っていた"?

Yes, 正しい and 好きだ are both expressed in a present form. I'll show you why.
We Japanese think "お前が正しい" is the present state at the time when 俺の心 accepted the state, because the state is judged not by the absolute time axis but by the relative axis in Japanese.
In other words, you have to ride on a time machine in Japan to interpret Japanese.
