Well of course it is a definite possibility.
But we have to look at
how it benefited India and what is the focused objective of decapitating the intelligentsia of a neighbor country. Pakistan Army had little such benefit, if any. They were largely a defeated entity, on the retreat. They could care less.
Did India benefit by having a leaderless Bangladesh without any intelligentsia for one generation? Sure it did.
All our foreign and domestic policy was decided either by India in New Delhi (or by planted agents and India friendly folks in Bangladesh, today's Chetona crowd) for the period between 1972-Aug. 1975 in rather permanent irreversible fashion, to India's express benefit. This is as clear as day to anyone alive then, and by anecdotal evidence to the next generation, including myself.
India profited to the tune of probably a Billion dollars yearly in trade and consumption of Indian goods in 1971, and more like $30 Billion a year today (if you count Indian revenues from medical tourism, Bangladeshis shopping in India, their people working in Bangladesh illegally etc. etc. 1971 was like a windfall to Indian Govt., the aftereffects being that they could eagerly suck dry the resources of Bangladesh in various ways.
Bangladesh suffered several famines and crises before 1975 which actually helped the legitimacy of the cause of the Bangladesh Army Coup-D'Etat planners to assassinate Sk. Mujib. People were sick of BKSAL and Mujib's plan of a special personal guard army being trained by India. The Army was being passed over in funding to help form this new armed entity (Rakkhi Bahini) and Mujib was planning dynastic politics with India's help. The excesses of his two sons (Extravagant weddings/parties while people starved, bloodless Bank Heists and kidnapping of pretty army wives) were icings on the cake. This is all part of history. I hate to say they deserved what was coming to them (even Serniabat and Sheikh Moni), but history bites your a$$ in strange ways when you commit transgressions. Allah does not like transgressors.
The people of Bangladesh have never admitted or appreciated domination by foreign entities like India, and today is no different.
They held us hostage economically for over fifty years, foisted things like Teesta and Farakka (and a dozen other) dams illegally withdrawing upper riparian water and turning our lands into desert in the lean season. This is still continuing.
Because of being a captive market of India, our own industries (despite being a large enough market) never developed, until most recently. Balance of trade was in their favor twenty to one back in the day, and it is still ten to one today. They forcibly push their low quality product in our market and make 100% sure they don't face ANY tariff barriers in Bangladesh market, while they throw everything they have tariff-wise to our exports to India.
The benefits of killing off our intellectuals helped India directly to the tune of more than about $700 Billion trade-wise since 1971 in my humble estimation, and that may be an under-estimation. They could not have done this if we had intellectuals opposing these one-sided India-friendly trade policies and reversed them with the help of oppositions and public opinion.
Being a 'Friend of India' cost us dearly.
Compare that to China, where our exports are more or less free from any type of tariff. Just a different mentality.
Indians often wonder why Bangladeshis hate their govt. so much. Well - seek the truth and ye shall find.
They made sure Hasina was an India stooge from day one (2nd phase of dominating our politics from the 2000s), though that is slowly changing.
Our exports saved us, and investors from other countries (most specifically, China) did too.
