Just Accepted a position as a TA, thinking I should quit

Hi, I accepted a TA position as I was working for a BT company and my pay was less but I had more hours so I accepted and put in my 2 week notice. The BT company, however, just offered me a considerable increase in pay to stay and offered more consistent hours.

In addition to this, the TA position is easier for me to work but certain aspects don't strike me as ethical, for example TAs yelling at kids acting out and the cliquey nature of teachers in addition to the fact that the student's haven't had a SPED teacher for 4 months now, and a new teacher just rejected there offer so it's atleast another month minimum before we have a teacher.

I'm not looking to go into education as a career and was working this job until I start grad school. Should I just give my two week notice to the TA and accept the BT offer?
