Waheguru Ji Ka Khalsa, Waheguru Ji Ki Fateh Jaskiratjio,
It is suicide and not shaheedi, because following Gurmat is kanio tikhi, as my masi says truly so, the more one tries, the tougher the tests Gurujio imposes on us.
NS44jio, ironic that your relative (http://www.sikh24.com/2012/05/missing-pardeep-singh-from-birmingham-uk/) looks so much like my masi's son, who also did same, torn between pleasing mother and wife, also was a Gursikh, then cut his hair, and shaved after marrying Canadian wife.
His father, was a Giani, and my cousin was inspired to follow Gursikhi and greatly inspired by Guru Gobind Singhjio, but left his Khalsa roop after marriage, soul weakened to pressures of life, as I am weakening but know cause is because disobeyed Gurujio's Hukam for amritvela, living amongst Sat Sangat, depending on mortal for help, instead of having strong faith in Him; Waheguru, the giver of pain, and happiness to lead us, as this world has been, and always will be each one for his or herself, though this rule doesn't apply to Gurujio's Gems, who will risk their all, and lives for another Gursikh, because they are Var Var Guru Vitho!
Bhul chuk muaf
