All he did is/was.......

[subhajit123]

Which one is grammatically correct?

1- All he did is what everyone should do.

2- All he did was what everyone should do.

Hi teachers, I think the first one is grammatically correct. The second one must be "all he did was what everyone should have done."

Can someone please help me?

They are both correct.

In fact, all three are correct, depending on the context.
