Is TK'ing Ever Justified? | GSOR 1008 | World of Tanks: Console

In this video CRZY_HRSE_LXIIX is running the T110E4 and doesn't take kindly to being bumped by his teammate, me who is running the lighter GSOR 1008. His response was to try and team kill me. Doesn't that hurt the team as a whole? Watch the replay and let me know your thoughts. Thanks.
