In a RC circuit is voltage through a capacitor always consider negative no matter if you're going with or against the current when setting up a voltage equation?

Short answer no.

Travelling with the current the voltage is negative (eg a Voltage drop). Against it, positive.

It's a DC. We will not be covering AC until a couple more weeks.

Ok in which case there is only current flowing while the capacitor is charging.

My understanding is current could also flow when the capacitor is discharging.

I don't know what you mean by the wording of your question. It would be better if you came up with some schematics on which you can base your question.
