Does the word times need an apostrophe after the e?

Often time’s harmful words were accompanied by acts of violence towards Jews as well.

No!! Do not use an apostrophe for a plural. Apostrophes are used to show possession.

K do I need a comma after times then? and if not could the sentence be improved?

No comma is needed in this sentence.

You should also omit the word "times" -- using the word "often" is all you need.

In this sentence, the word "times" does not require an apostrophe after the 'e'. The usage of an apostrophe after the 'e' (as in "time's") would indicate possession or contraction, which is not the intended meaning in this context. The sentence should therefore be written as:

"Often times harmful words were accompanied by acts of violence towards Jews as well."

To determine whether or not an apostrophe is needed, you can consider the function of the word in the sentence. In this case, "times" is used as a plural noun to refer to multiple occasions or instances. Plural nouns in English generally do not require an apostrophe unless they are used to indicate possession (e.g., "the birds' nests") or contraction (e.g., "it's" meaning "it is").
