When analyzing literature, it needs to be done in the present tense. Literature lives as you read; it never happened, it is always happening.
Pretend this is part of an essay
For example, when "Dill [leaves them] early in September... [they see] him off on the five o'clock bus."
We don't refer to dead people as still being wrong or right. They are neither, since they are dead (or if you prefer, they now have access to better information).
So you cannot say either Einstein is right or Einstein is wrong.
When referring to opinions living people expressed in the past, it is usual to use the past tense, unless you are certain that the opinion is still held by that person. So here you would say Einstein and Tarantino were wrong, since you don't actually know Tarantino's present opinion on the subject.
If you want to express that this is still Tarantino's opinion, your best option is "Einstein was, and Tarantino is, wrong" or possibly "Einstein was wrong, and Tarantino is wrong", or "Einstein was wrong, as Tarantino is", and so on.
To refer to two subjects, one in the past tense and one the present, you need two verbs, one past tense and one present.

There is a very useful rule which I found in one of video lessons on the Internet, and it turned to be very useful. If you start speaking in present, keep to the present, if you start speaking in the past, keep to the past.It really helps while making sentences. So if you began your story in the past, it would be right to continue in the past. Thus you will avoid a mistake.
