But -- The Greek word translated as "but" means "but," "however," and "on the other hand." It joins phrases in an adversarial way. Since it always falls in the second position, translating it as "however" often captures its feeling better.  It can also be an explanation of cause ("so").

if -- The "if" here expresses a condition but it means nothing regarding whether that condition is met or not. It also means "if ever" and "whenever." -- The "if" here expresses a condition but it means nothing regarding whether that condition is met or not.

I -- This is from the first-person, singular form of the verb.

do,-- The Greek word translated as "to do" has the primary meaning of "making" or producing" something or "causing" or "performing" as service. It describes a productive action.  It is not as broad a word as the English "do," which covers all actions, productive or not. 

them, -- This English objective pronoun is added and not in the Greek source.   In Greek, pronoun objects are not repeated after each verb because they are implied by their first occurrence.

even though  --  "Though" is a conjunction that means "and if," "even if," and "although."  It is a contraction of the conjunction "and" that joins and the particle that indicates a possibility.

The sense is that "you don't want" or "think" something, not that it isn't done or thought.   With the verb "to be," the sense is "doesn't seem." When a negative precedes the verb, it affects the whole clause. When it precedes other words, its force is limited to those words. This is the negative used with commands or requests. Used with an imperative to express a will or wish. Used in negative "when" and "if" clauses.
