Anyways, because i thought the nature of my request is custom, i would rather go implementing it myself.
The problem, mainly, is that you're logging things as the same user you want to monitor. This means, by definition:
- Everything you log, they can delete.
- Everything you do, they can undo.
- Everything you run, they can kill.
- Everything you make, they can destroy.
This leaves it wide-open to both intentional and accidental abuse. There is no amount of shell script alone you can write to avoid this.
To prevent users from deleting the stuff being logged about them, it has to be logged somewhere they can't control. Meaning, the logging code has to run as some other user.

UTMPX(5) BSD File Formats Manual UTMPX(5)
NAME
utmpx, wtmpx, lastlogx -- user accounting database
SYNOPSIS
#include <utmpx.h>
DESCRIPTION
In contrast to utmp and wtmp, the extended databases in utmpx and wtmpx reserve more space for logging hostnames, and also information on a
process' ID, termination signal and exit status.
The <utmpx.h> header defines the structures and functions for logging user. Currently logged in users are tracked in /var/run/utmpx, a list
of all logins and logouts, as well as all shutdowns, reboots and date changes, is kept in /var/log/wtmpx, and the last login of each user is
noted in /var/log/lastlogx.
The interface to the utmpx file is described in getutxent(3).
The wtmpx file can grow rapidly on busy systems, and is normally rotated with newsyslog(8).
In the event of a date change, a shutdown, or a reboot, the following items are logged in the wtmpx file:
date The system time has been manually or automatically updated by date(1). The command name date is recorded in the field
ut_name. In the field ut_line, the character '|' indicates the time prior to the change, and the character '{' indicates
the new time.
reboot
shutdown A system reboot or shutdown has been initiated. The character '~' is placed in the field ut_line, and reboot or shutdown
in the field ut_name (see shutdown(8) and reboot(8)), using logwtmpx(3).
FILES
/var/run/utmpx The utmpx file.
/var/log/wtmpx The wtmpx file.
/var/log/lastlogx The lastlogx file.
