OnEdit Cell Index not working with multiple inputs - google-apps-script

Question

I'm trying to write a piece of code that whenever someone on our rosters is terminated it will capture their data, put them into a "termed associates" sheet and delete them from the roster.
The code I wrote works fine for single instances of the change (though it is a bit slow), but the main problem is if I change multiple people to "TERM" in quick succession, it breaks and sometimes will delete rows that aren't the row meant to be deleted.
Here's my code:
const ss = SpreadsheetApp.getActiveSpreadsheet();
const termSheet = ss.getSheetByName('Term Tracker');
const check = SpreadsheetApp.getActiveSheet().getActiveCell().getValue();
function deleteTerm() {
if(check == 'TERM'){
//grabs the cell that has just been edited, finds the index of the row
let sheet = ss.getActiveSheet();
let cell = ss.getActiveCell();
let index = cell.getRowIndex();
//grabs data and posts to new sheet
//grabs values to inset into email
let read = sheet.getRange(index,1,1,55).getValues();
let name = sheet.getRange(index, 4).getValue();
let shift = sheet.getRange(index,1).getValue();
termSheet.insertRowBefore(2);
termSheet.getRange(2,1,1,55).setValues(read);
//deletes the index row
sheet.deleteRow(index)
//mails me a notification someone was termed
MailApp.sendEmail({
to: "{myemail}",
subject: "New Term, " + name ,
body: "There is a new term of " + name + ", please confirm the term reason and term date.
They are on the " + shift + " roster"
});
}}
Any ideas on exactly what I'm doing wrong? I'm still very new to coding, so I'm sure that the code isn't very great. Any feedback would be lovely as well. :)

This should work faster
But any expectation of consistently fast response for an onEdit function is a hopeless wish that is not going to be fulfilled. You must be patient and give it time to operate.
function onEdit(e) {
const sh = e.range.getSheet();
const tsh = e.source.getSheetByName('Term Tracker');
if (e.value == 'TERM') {
let vs = sh.getRange(e.range.rowStart, 1, 1, 55).getValues();
let name = vs[0][3];
let shift = vs[0][0];
tsh.insertRowBefore(2);
tsh.getRange(2, 1, 1, 55).setValues(vs);
sh.deleteRow(e.range.rowStart);
MailApp.sendEmail({to: "{myemail}",subject: "New Term, " + name,body: "There is a new term of " + name + ", please confirm the term reason and term date. They are on the " + shift + " roster"});
}
}
